We guarantee the authenticity of our listings. If the product you receive differs materially from what was described (i.e. if we accidentally shipped you the wrong product), contact us and we will make it right. We cannot control the end use of our products and make no guarantee as to their suitability for any particular application. As such, all products are sold as-is (that is, as described in the applicable listing) and all sales are final. If you encounter a problem with your use of any of our products, feel free to contact us, as we may be able to offer advise on how to correct the problem or we may be able to improve our products based on your feedback. However, we generally do not accept returns of products that were duly purchased.

See shipping details on individual listings. Unless otherwise specified, free shipping offers apply only to items shipped within the contiguous 48 states. At present, we do not sell products outside the United States.
