Every package we send has a USPS delivery confirmation tracking number. This is our proof of delivery. If your package is lost, and the carrier cannot give us confirmation of delivery, we will send you a replacement of your order at no cost to you. (If the carrier has proof of delivery, yet you say that you did not receive your package, you must file a claim directly with the carrier, using the delivery confirmation number we will provide for you). This guarantee does not cover replacement of items damaged by incorrect handling or carelessness.
