You can refund a portion of a product's price to a customer, rather than the full price.
You can provide a partial refund for a product. This refunds a portion of the price, from a minimum of $1 to a maximum of 90% of the price, to the customer. The refunded portion is drawn from the affiliate, vendor, and Joint Venture partner portions, proportional to the amount initially paid to each party. If the refunded amount exceeds the vendor, affiliate, and Joint Venture partner portions, the remainder is taken from the ClickBank portion.
You cannot issue a partial refund if the product price is less than $10, or if the product has a free trial plus shipping and handling.
You can only give a partial refund for a purchase once. However, you do have the option of refunding the remainder of the purchase price.
