        Acquiring a Return Merchandise Authorization (RMA) Number:

        Please call 866-258-1554 or email to receive a Return Merchandise Authorization number if there is any reason you would like to return your order. All charges to ship merchandise back are the responsibility of the customer. There will be a 10% re-stock fee on all returned orders, unless a replacement order has been made. Customers are given 7 days from the delivery date to contact us for a RMA number. Returns must be received back to our warehouse within 90 days. Fees may change based on extended time passing.

        Returns of open/used products are not accepted.

        Special order items are not returnable and are designated on the specific product pages.

        InstallerStore strongly encourages choosing a shipping method for your return where a tracking number and insurance can be obtained. Accounts will be credited back after inspection has been made to the product to ensure product has not been damaged in any way and can be resold. Packages damaged while being shipped back to us will not be accepted as a return and customer will be contacted. InstallerStore is not responsible for lost or damaged returns. It is the customer's responsibility to file a claim with the shipping company.

        Any merchandise that is shipped back without a RMA number will have a minimum re-stocking fee of 25% of the product cost and shipping charges will not be refunded.

        All returned products must be shipped directly to InstallerStore even if they were originally shipped from the manufacturer, unless otherwise told by InstallerStore. Shipping back to manufacturer may cause re-stocking fee to increase.
