• Residential freight generally includes curbside delivery only. Liftgate service, appointments, inside delivery, redelivery, or other special services may result in additional charges.

Order Changes & Cancellations

• Please contact us as soon as possible if you need to change or cancel an order. We will make every reasonable effort to accommodate the request, but cancellation is not guaranteed once processing has begun.
• Special-order, made-to-order, custom, built-to-order, and drop-shipped products may not be cancellable once the order has been submitted to the manufacturer or supplier or production has begun.
• If a manufacturer or supplier allows a cancellation but imposes a cancellation, processing, restocking, shipping, or other fee, those charges may be deducted from the amount refunded.
• Orders that have already shipped must be handled as a return and are subject to the return terms and fees below.

Returns & Refunds

Eligible items may be considered for return within 30 days of delivery. All returns require prior authorization from PAD Overland. Return requests are subject to our return policy as well as any applicable manufacturer or supplier return requirements.

Restocking & Return Fees

• In addition to the 35% PAD Overland restocking fee, the customer is responsible for any return, restocking, cancellation, processing, handling, shipping, or freight fees imposed by the manufacturer, supplier, or distributor.
• Applicable fees will be deducted from the amount otherwise eligible for refund.
• Original shipping charges are non-refundable unless the return is due to an error made by PAD Overland or otherwise required by applicable law.

How to Start a Return

1. Contact PAD Overland with your order number, the item you would like to return, and the reason for the return.

3. Do not ship an item back to PAD Overland, the manufacturer, or the supplier without prior authorization. Unauthorized returns or products sent to the incorrect location may be refused.
4. Package the product securely with all original components and paperwork. Insured, trackable shipping is strongly recommended.

Refunds

• Approved refunds will be issued to the original payment method after all applicable restocking, supplier/manufacturer, shipping, freight, or other authorized return deductions have been calculated.
• Original shipping charges and return shipping costs are non-refundable unless the return is due to an error made by PAD Overland or otherwise required by applicable law.
• Once a refund has been issued, additional processing time may be required by your bank or credit card provider.

Damaged, Defective, or Incorrect Items

• Please contact us within 7 days of delivery if your order arrives damaged, defective, incomplete, or different from what you ordered.
• Please provide your order number along with clear photos of the product, packaging, and shipping label.
• For freight damage, please note visible damage with the carrier at delivery and take photos before signing whenever possible.
• The standard 35% PAD Overland restocking fee does not apply when PAD Overland determines that a return is required because we shipped the incorrect product or because an item arrived damaged or defective and a return/refund is the approved resolution.
