Return Policy


We make returns as easy as possible. Our mission is to provide you with the best products and the best service in the industry. We understand that sometimes, customers change their minds about products that they order or simply do not need them anymore. We also know that customers are cautious about Return Policies since they are often tricky and misleading. Our goal is to make the return or exchange process trustworthy and as simple as 1-2-3.


If for any reason you are not completely satisfied with your purchase, you may return the item within 14 days of delivery of your order. For orders placed during the holiday season from November 15th to December 31st, the return period is extended to 60 days.

The following rules apply:

  • Products must be in original packaging and in a new and resalable condition.
  • Any product that was used or fully/partially installed is non-returnable.
  • Shipping Fees are non-refundable.
  • All returns must be made via our Return Procedure by filling out an RMA form in the MY ACCOUNT section.
  • There are few non-returnable products & services that may be offered on our website. It will indicate clearly in the product description if a different return policy applies.
  • Order cancellations can only be requested prior to shipment or in some cases.
  • If the return of an item was caused by an error on our or a manufacturer's part, we will cover the shipping fees.


To return a product, you must first request a Return Merchandise Authorization (RMA) that is located in the MY ACCOUNT section next to each order item that you want to return. The RMA form will include an exact return address and detailed instructions on how to return a product. Please allow 24 to 72 hours for processing your claim.


There are 2 ways you can go about exchanging a product:

  • Option 1 (Slower) - Use the standard return procedure to request an RMA for the part you need exchanged. In your request please specify the exact item(s) you would like to exchange to. Upon receipt of your returned product we will process an exchange and ship the new part. If there is a difference in the price, you will be either refunded or charged the difference.
  • Option 2 (Faster) - Order the new part online or over the phone so it can be shipped to you right away. Then request an RMA using a standard Return Procedure for the part you would like to return. Upon return of the part a refund will be issued promptly.


We all know that accidents happen sometimes. If your product(s) will arrive defective, damaged, or simply incorrect, please contact our customer service department as soon as possible. Please do not attempt to use or install the part! We will send you a replacement part and provide you with a prepaid return label to return the defective part. Product(s) must be returned to us within 30 days. If the damage was caused by a shipping courier, we will schedule a damage pick up by the courier.

When a replacement part is requested to be shipped prior to the return of original merchandise, we must temporarily authorize your credit card until the original merchandise is returned.


When you request a cancellation of an order or a part it may take up to 72 hours to process your cancellation claim. This process may involve voiding orders in computer systems, removing items from backorder logs, having operations personnel pull items from production schedules and sometimes stopping orders at the shipping dock. Also note that sometimes products ship more quickly than expected, so we recommend that you do not purchase alternative products until receiving final confirmation of your cancellation.


After we accept your return, you will be issued a refund via the same payment method as you had originally used to place the order (Credit Card, Paypal, Google, eBillMe, or Check). The refund amount will be composed of the original purchase price minus shipping charges. You will be sent an email confirming receipt of the return and your credit. Please allow an additional 5-7 days for the credit to appear on your account.
