        Incorrect or Damaged Product

        If you have received damaged merchandise or have received items that you did not order, please contact us by replying to your e-mail receipt, making sure to copy the contents of the receipt in your e-mail. Simply let us know the error or that the product was damaged, and we'll take care of it at no cost to you, including all shipping charges (up to the original amount you paid for shipping). We will wait to receive and inspect the originally-shipped product prior to shipping a replacement. If a product was damaged during shipping, you must retain all materials until the shipper (UPS, FEDEX, etc.) has had a chance to inspect the package, if they choose. Our policy is to replace damaged or incorrect products. If you choose not to accept a replacement, it is considered a regular return and subject to our return policy guidelines listed above.

        Replacement Product

        Warranty Replacement

        If you feel a product you have purchased is defective or has failed under warranty, contact us.

This will save you time and money if there happens to be another reason for the problem you are having with the product. Once a product has been determined it may be defective and requires further inspection, we will instruct you as to your next course of action. This next step may vary depending on the guidelines set forth by the manufacturer. Shipping costs for returning parts for inspection and returning the part to you are usually your responsibility depending on the manufacturer and what their warranty policy is. More information can be found in our Customer Service section under the Product Warranties section.
