Vitalyte offers a 30 day money back guarentee on all products, but you'll be responsible for all transportation charges. If we make the mistake, we will be responsible for all shipping charges. Authorization must be obtained from us for the return of goods. All requests for returns must be made within 30 days of receipt of goods. The returned package must be received within 15 business days after authorization of return. When returning products, we strongly recommend the use of a carrier that can track packages. You also assume responsibility for insuring the returned item. Unless we make the mistake, shipping charges are not refundable and we will not pay the return shipping charges.
