When a product is returned, the customer generally receives a full refund. Payouts from that sale are debited back out of the corresponding vendor and affiliate accounts. Due to the digital format of ClickBank products, when a product is returned the customer retains the product and, in many cases, the customer has received a benefit from the product prior to the return. In such cases, ClickBank reserves the right to issue a refund for less than the full purchase price.
