Your satisfaction is 100% guaranteed. If you are dissatisfied with your Quaffers for any reason, simply return the product within 60 days for an easy refund of your purchase price, excluding shipping and handling. For a return and refund, the original purchaser must contact our service center by email at info@quaffer.com and obtain a return authorization number (RMA). The purchaser must then pack the product securely and send it postage paid to the address specified on the RMA advice. Refunds will only be made to the name, address, and credit card account on file. Returns received without an RMA may delay any refund due and may incur additional processing charges.
