Refund Policy
Last Updated: September 4, 2026
Effective Date: September 4, 2026
Okanagan RV Parts ("Company", "we", "us", or "our"), operating UsedRVParts.ca, supplies specialty new and used RV parts.
Due to the nature of RV parts, including compatibility differences, installation requirements, shipping logistics, manufacturer warranty processes, and industry-standard return practices, the following Return & Refund Policy applies to all purchases unless otherwise required by applicable law.
By placing an order, you ("Customer" or "Buyer") acknowledge that you have read, understood, and agree to this Return & Refund Policy together with our Terms of Service, Shipping Policy, Privacy Policy, and Legal Notice.
Nothing in this Policy is intended to exclude, restrict, or waive any statutory right, warranty, remedy, or consumer protection that cannot lawfully be excluded under applicable law.
1. Final Sale Categories – Non-Returnable Items
The following products are FINAL SALE and are not eligible for voluntary return, refund, or exchange, except where required by applicable law:
- Special order products
- Out-of-stock items specially obtained for a customer
- Obsolete or discontinued parts
- Custom-made or custom-requested products
- Batteries
- Chemicals, adhesives, sealants, lubricants, sprays, and aerosol products
- Generators
All purchases within these categories are final once an order has been accepted and payment has been successfully processed.
Customers are responsible for confirming compatibility before placing an order, including when a product has been identified, suggested, or recommended through our AI-powered shopping assistant or another automated feature.
2. Electronic Components – Final Sale
Electronic components, including circuit boards, control boards, electronic modules, sensors, igniters, displays, and similar electrical components, are FINAL SALE.
These items:
- Are final sale and are not eligible for voluntary return or refund.
- Must be diagnosed and handled through the applicable manufacturer warranty process where appropriate.
- Cannot be accepted for return once shipped, except where required by applicable law.
Important
Due to the high rate of damage resulting from improper installation, incorrect diagnosis, electrical damage, and part swapping, electronic components may be inspected, tested, documented, or serialized before shipment.
Customers are responsible for proper diagnosis and compatibility verification before ordering electronic components.
A recommendation or identification made by our AI shopping assistant does not replace proper diagnosis or independent compatibility verification.
3. Returns for Eligible New Parts
We accept returns on eligible new, unused products subject to the following conditions.
Return Requirements
To qualify for a return:
- A return request must be submitted within 30 days of confirmed delivery.
- The item must be unused, uninstalled, and in resalable condition.
- All original packaging, manuals, accessories, labels, and components must be included.
- The returned item must pass inspection upon receipt.
Failure to satisfy these requirements may result in the return being refused or a reduced refund where permitted by applicable law.
Restocking Fees & Return Conditions
These return conditions reflect standard practices throughout the RV parts and specialty components industry, where many products cannot be resold once installed, handled, or removed from their original packaging.
The following conditions apply to eligible returns:
- Minimum 20% restocking fee.
- Return shipping is the responsibility of the Buyer.
- Original outbound shipping charges are non-refundable.
- Signature confirmation fees are non-refundable where applicable.
Refunds are issued to the original payment method within approximately 7 business days after the returned product has been received, inspected, and approved.
Non-Returnable New Products
The following products are not eligible for voluntary return or refund, except where required by applicable law:
- Installed products
- Products damaged after delivery
- Products altered or modified after delivery
- Products missing original components
- Products returned without original packaging where resale is no longer reasonably possible
Orders confirmed as delivered by the carrier—including tracking confirmation, delivery scan, proof of delivery, delivery photograph, GPS confirmation, or signature confirmation where applicable—are considered fulfilled orders, subject to any rights or remedies available under applicable law.
4. Used RV Parts – Final Sale
Unless otherwise expressly stated, all used RV parts are sold:
AS-IS • WHERE-IS • WITH ALL FAULTS • FINAL SALE
Each used product is visually inspected and, where reasonably possible, tested prior to shipment to confirm it is functioning at the time of sale.
Because used parts vary in age, condition, previous use, configuration, and application:
- Fitment and compatibility are the Buyer's responsibility.
- Installation is the Buyer's responsibility.
- Customers must independently verify applicable part numbers, model numbers, specifications, dimensions, configuration, and compatibility information before ordering.
- Cosmetic wear, scratches, fading, discoloration, or signs of previous use may be present.
No voluntary return, refund, or exchange will be accepted for:
- Incorrect orders
- Buyer error
- Installation issues
- Compatibility issues
- Change of mind
A product being identified, suggested, linked, discussed, or recommended by our AI shopping assistant does not alter the final-sale status of a used product or constitute a guarantee of compatibility.
Nothing in this section limits any consumer rights that cannot lawfully be excluded under applicable law.
5. AI-Assisted Product Recommendations & Compatibility
UsedRVParts.ca may provide an AI-powered shopping assistant or other automated functionality to help customers search for products, identify potentially relevant parts, compare products, understand product information, or obtain general compatibility information.
The AI shopping assistant is an automated system and can make mistakes.
AI-generated responses may contain:
- Incorrect product recommendations
- Incorrect compatibility or fitment conclusions
- Incorrect specifications
- Outdated information
- Incomplete information
- Misinterpretations of customer questions
- Incorrect assumptions
- Omissions
- Information relating to a similar but different product, model, revision, or configuration
AI Recommendations Are Not Fitment Guarantees
A product being recommended, suggested, displayed, linked, discussed, or identified by our AI shopping assistant does not constitute a guarantee or warranty that the product will fit, function with, or otherwise be suitable for a particular RV, appliance, vehicle, or application.
Before ordering, customers are responsible for cross-referencing the actual product listing with their application.
Depending on the product, customers should verify relevant information including:
- Manufacturer part number
- Existing part number
- RV, appliance, vehicle, or component model number
- Serial number
- Production date or revision
- Listed compatible models
- Dimensions
- Voltage and electrical specifications
- Connector type
- Mounting arrangement
- Orientation
- Plumbing or propane configuration
- Size
- Colour or configuration where relevant
- Included components
- Manufacturer documentation
- Other applicable compatibility information
Similarity in appearance, product name, model family, dimensions, or part number does not by itself establish compatibility.
If compatibility remains uncertain after reviewing and cross-referencing the product listing, customers should consult a qualified RV technician before ordering.
Effect on Return Eligibility
An AI-generated recommendation does not, by itself, change the return eligibility or final-sale status of a product under this Policy.
Where a customer orders an incompatible product after relying on an AI-generated recommendation without independently verifying the applicable product listing and compatibility information, the normal terms of this Return & Refund Policy continue to apply, to the fullest extent permitted by applicable law.
For an otherwise return-eligible product, this generally means that applicable:
- Return deadlines
- Product-condition requirements
- Packaging requirements
- Restocking fees
- Return shipping charges
- Original outbound shipping terms
continue to apply.
For a product that is otherwise FINAL SALE, an AI recommendation does not, by itself, create a voluntary right of return.
To the fullest extent permitted by applicable law, an AI-generated recommendation does not, by itself, make Okanagan RV Parts responsible for return shipping, original outbound shipping, installation, removal, reinstallation, diagnostic, labour, travel, or other costs resulting from incorrect customer-selected fitment.
However, nothing in this section excludes or limits any return, refund, warranty, statutory remedy, or other consumer right that cannot lawfully be excluded or limited.
Conflicting Information
If information supplied by the AI shopping assistant conflicts with:
- The applicable product listing
- Manufacturer documentation
- A confirmed manufacturer part number
- A product label
- Serial-number requirements
- Published specifications
- Information supplied by a qualified technician
do not rely on the AI-generated information without further verification.
Customers should seek clarification or qualified technical assistance before ordering where a material compatibility discrepancy remains unresolved.
6. Defective Products & Manufacturer Warranty
UsedRVParts.ca is not the manufacturer and does not independently provide manufacturer warranties on new products unless expressly stated otherwise.
If a product is believed to be defective:
- It should first be diagnosed by a qualified installer or technician.
- Manufacturer warranty claims must generally be submitted directly to the manufacturer in accordance with their warranty procedures.
We are happy to assist by providing:
- Manufacturer contact information
- Proof of purchase
- Original invoice documentation
- Available product information where appropriate
UsedRVParts.ca does not:
- Approve manufacturer warranty claims
- Determine warranty eligibility
- Replace products under manufacturer warranty unless authorized by the manufacturer
- Accept returns solely because a manufacturer warranty claim exists
An AI-generated troubleshooting response, diagnosis, or product recommendation does not constitute a manufacturer warranty determination or professional diagnosis.
7. Installed Products
Any product that has been installed, modified, altered, wired, connected, or otherwise placed into service is considered used and is not eligible for voluntary return or refund, except where required by applicable law.
Customers should therefore complete all reasonable compatibility checks before installation.
Installing a product based solely on an AI-generated recommendation without independently confirming compatibility does not, by itself, create return eligibility.
8. Shipping, Delivery & Risk
Shipping practices are governed by our Shipping Policy, which forms part of this Return & Refund Policy.
Delivery estimates are provided for convenience only and are not guaranteed unless expressly stated otherwise.
The Buyer is responsible for:
- Providing a complete and accurate shipping address, including apartment, suite, unit, lot number, business name, gate codes, or any other information necessary for successful delivery.
- Monitoring shipment tracking.
- Ensuring the delivery location is secure and accessible.
- Being available for signature-required or scheduled freight deliveries where applicable.
UsedRVParts.ca may require signature confirmation at its discretion, particularly for higher-value or higher-risk shipments.
Risk of loss passes to the Buyer in accordance with applicable law and the applicable carrier's terms where legally permitted.
Carrier tracking records, delivery scans, proof of delivery, delivery photographs, GPS confirmation, and signature confirmation where applicable may be relied upon as evidence of delivery and fulfillment.
To the fullest extent permitted by applicable law, UsedRVParts.ca is not responsible for:
- Carrier delays
- Severe weather delays
- Customs delays
- Delivery access issues
- Failed delivery attempts caused by incorrect or incomplete customer information
- Theft occurring after confirmed delivery
- Porch piracy
Claims involving shipping damage or loss may need to be handled through the applicable carrier, supplier, manufacturer, or insurer depending on who controls the shipment and applicable shipping arrangements.
We will provide reasonable assistance with documentation where appropriate.
9. Shipping Damage & Claims
All shipments are packaged using commercially reasonable packaging methods appropriate for the products being shipped.
Upon delivery, Buyers should:
- Inspect all packages immediately.
- Note visible damage with the carrier before accepting delivery where possible.
- Report shipping damage within 5 business days of delivery.
For shipping damage claims, we may request:
- Photographs of the damaged product.
- Photographs of all packaging.
- Shipping labels.
- Delivery documentation.
- Any additional information reasonably required by the carrier or supplier.
Claims may need to be submitted through the applicable carrier, supplier, manufacturer, or insurer depending on the shipping arrangement.
UsedRVParts.ca will reasonably assist customers throughout the claims process but cannot guarantee claim approval or claim outcomes.
10. Undeliverable, Refused & Returned Shipments
The Buyer is responsible for providing complete and accurate shipping information.
If a shipment is returned to UsedRVParts.ca or our supplier due to circumstances including, but not limited to:
- Incorrect or incomplete shipping address
- Unclaimed shipment
- Refused delivery
- Mid-transit cancellation
- Failure to accept a signature-required delivery

- Orders returned because of failed delivery attempts or refusal of delivery will be treated as refused shipments under this Policy.
Nothing in this section limits any rights that cannot lawfully be excluded.
11. International Orders
For international shipments, the Buyer is responsible for applicable:
- Customs duties
- Import taxes
- Brokerage fees
- Other government charges or import costs
Failure to pay applicable import charges may result in:
- Return shipment at the Buyer's expense
- Applicable restocking fees
- Additional carrier charges
These provisions apply subject to applicable law.
12. Payment Verification & Fraud Prevention
To help protect our customers and business, all orders are subject to payment authorization, fraud screening, and risk assessment.
UsedRVParts.ca reserves the right, subject to applicable law, to:
- Cancel or refuse an order.
- Request identity or payment verification.
- Hold orders pending fraud review.
- Require signature confirmation for higher-risk shipments.
- Delay shipment while additional verification is completed where reasonably necessary.
Orders reasonably suspected of fraud, unauthorized payment activity, abusive reshipping practices, or deliberate misuse of our policies may be cancelled.
13. Chargebacks & Payment Disputes
Customers are encouraged to contact us first if they believe there is an issue with their order so we have an opportunity to investigate and resolve the matter.
Where a payment dispute or chargeback is initiated, UsedRVParts.ca reserves the right to provide relevant supporting documentation, including:
- Proof of delivery
- Carrier tracking records
- Delivery photographs
- GPS confirmation
- Signature confirmation where applicable
- Order confirmations
- Customer communications, including relevant website-chat communications where lawfully retained
- Applicable policies
- Return records
- Product documentation
- Product listings
- Compatibility information presented at the time of purchase where available
Carrier tracking records, proof of delivery, delivery photographs, GPS confirmation, and signature confirmation where applicable may be relied upon as evidence of delivery and fulfillment.
Nothing in this section limits any rights available under applicable payment network rules, consumer protection legislation, or other applicable law.
14. Limitation of Liability
To the fullest extent permitted by applicable law, UsedRVParts.ca's liability is limited to the purchase price of the applicable product.
To the fullest extent permitted by applicable law, UsedRVParts.ca is not responsible for indirect, incidental, special, or consequential losses or expenses, including:
- Installation or labour costs
- Diagnostic costs
- Removal or reinstallation costs

Where liability cannot lawfully be excluded or limited, it will be limited only to the extent permitted by applicable law.
