We'll pay the return shipping costs if the return is a result of our error (you received an incorrect or defective item, etc.). Please contact our shipping department for prior authorization to use our Fedex or UPS account number for the return. All return goods must be authorized in advance by Sarasota Avionics. A copy of the sales invoice should be placed inside the package to avoid delay in processing your return. If you do not have the original receipt, please let us know and one will be emailed or faxed to you. The customer is responsible for all return shipping charges, including duties and taxes if applicable. A 15% restock fee will be charged for all stock item returns. If an order was shipped with our free ground promotion, actual shipping charges will be deducted from the refund total. No returns will be accepted after 30 days from date of shipment. All special orders or "as is" sales are final. Refunds are issued in the original form of payment only. Cash purchases will be refunded in the form of a check. Credit card refunds will be issued to the same credit card used on the original order. Please allow 10 business days after receipt for your return and refund to be processed.
