Returns Policy

You may return most new, unopened items within 30 days of delivery for a full refund. We'll also pay the return shipping costs if the return is a result of our error (you received an incorrect or defective item, etc.).

You should expect to receive your refund within four weeks of giving your package to the return shipper, however, in many cases you will receive a refund more quickly. This time period includes the transit time for us to receive your return from the shipper (5 to 10 business days), the time it takes us to process your return once we receive it (3 to 5 business days), and the time it takes your bank to process our refund request (5 to 10 business days).

If you need to return an item, please Contact Us with your order number and details about the product you would like to return. We will respond quickly with instructions for how to return items from your order.
 

Contact Customer Service for a Return Materials Authorization (RMA) number before returning any merchandise for any reason. The TRUCK AND AUTO PARTS STORE is not responsible for any merchandise returned without an RMA number. Returned merchandise will be inspected and may be subject to a restocking fee. Absolutely no returns on sale items, unless the item was received in a damaged condition and an RMA number is requested within 5 days of receipt of shipment.   


RETURNS & RESTOCK FEES  

RETURN OF “ON SALE”, “CLEARANCE”, OR ANY OTHER PROMOTIONAL DISCOUNT ITEMS
Items sold as “On Sale” or “Clearance” or “Special Promotional Discount” can be exchanged but not returned. All items sold, regardless of price, have passed our Quality Control inspections, and are deemed to be in saleable condition.  

RETURNS FOR REFUND  

Any item returned for a refund will be accepted for full refund, LESS a 25% RESTOCKING FEE, provided that the item is returned to us within 30 days of the date when we shipped it to the customer. Returned to us means IN OUR POSSESSION on or before the 30th day after our shipping date. The cost of shipping the item to us must be paid by the customer - items returned COD will be rejected, and no refund will be made. Returned items must be unworn, undamaged, and all the tags and labeling must be intact and attached to the item with their original attachments. Returned items that do not meet these criteria will not be refunded, nor will they be returned to the customer unless the customer pays for shipping and also pays a handling fee.  

An item that is returned for refund will be credited to the card used for the purchase within seven business days. All refunds will be applied to the credit/debit card used for the original transaction - in no circumstances will a refund be credited to a different credit/debit card, nor will a refund ever be issued as a check or money order. The refund will be limited to the cost of the item, less restocking fees when applicable. The original cost of shipping the item to the customer will not be refunded.  

RETURNS FOR EXCHANGE  

We will accept an item returned for exchange provided that the item is returned to us within 30 days of the date at which we shipped it to the customer. Returned to us means IN OUR POSSESSION on or before the 30th day after our shipping date. The cost of shipping the item to us must be paid by the customer - items returned COD will be rejected, and no exchange will be made. Returned items must be unworn, undamaged, and all the tags and labeling must be intact and attached to the item with their original attachments. Returned items that do not meet these criteria will not be exchanged, nor will they be returned to the customer unless the customer pays for shipping. When an item returned for exchange has been determined to qualify for exchange the exchange will be made and the replacement product shipped within seven business days.  

Returned items may be exchanged for any item currently in stock, in any size currently available. However, if the requested item is priced lower than the returned item, the customer will not receive a credit for the difference. If the requested item is more expensive that the returned item, then the difference will be charged to the same credit card that was used for the original transaction.  

The exchanged item will be shipped to the same shipping address as the original item, using the same shipping method as the original item, and the cost of shipping will be charged to the credit card that was used for the original transaction.  

When an item is returned because of a manufacturing defect that has been determined to qualify as defective (if it is in our possession by the 30th day after our shipping date, and our Quality Control team has confirmed that the defect in the item is in fact a manufacturing defect and not damage caused by wear or accident in use), the item will be replaced or exchanged or a refund will be issued in accordance with the customer's choice.  

The returned item may be replaced with the same style in the same size at no charge regardless of the current selling price of the item (provided it is still available). Alternatively, it may be exchanged for any item currently in stock, in any size currently available. However, if the requested item is priced lower than the returned item, the customer will not receive a credit for the difference. If the requested item is more expensive that the returned item, then the difference will be charged to the same credit card that was used for the original transaction. If replaced or exchanged, the item will be shipped to the same shipping address as the original item, using the same shipping method as the original item, free of charge.  

If a refund is requested, it will be applied to the credit/debit card used for the original transaction - in no circumstances will a refund ever be credited to a different credit/debit card, nor will a refund ever be issued as a check or money order. The refund will be limited to the cost of the item - the original cost of shipping the item to the customer will not be refunded.  

THE TRUCK AND AUTO PARTS STORE WILL NOT ACCEPT RETURN OF OR ISSUE CREDIT FOR THE FOLLOWING ITEMS (INCLUDING, BUT NOT LIMITED TO): 

  • Batteries
  • Gloves
  • Any special order products (including but not limited to): specific apparel fits, vehicular modification or customization products, any hard goods requiring special embellishment, any product purchased for fulfillment of agency purchase order.  

 

OVERWEIGHT OR FREIGHT ITEMS 

Some Items may require a handling charge. The price of shipping is calculated at checkout but it may not be accurate and a customer service representative will contact you to inform you of such a problem. Sometimes a shipping charge will be more because it is oversize or it may be less due to being able to package together as a single unit. Also overseas or out of country orders may have increased charges. You order will be put on hold until the changes in shipping cost can be approved or disapproved.

TYPOGRAPHICAL & SYSTEM ERRORS 

In the event that a product is mistakenly listed at an incorrect price, the TRUCK AND AUTO PARTS STORE reserves the right to refuse or cancel any orders placed for product listed at the incorrect price. The Truck and Auto Parts Store reserves the right to refuse or cancel any such orders whether or not the order has been confirmed and your credit card charged. If your credit card has already been charged for the purchase and your order is cancelled, the Truck and Auto Parts Store shall issue a credit to your credit card account in the amount of the incorrect price. 

TERM; TERMINATION
