WooCommerce Store Credit

Generate store credit coupons that enable customers to make multiple purchases until the total value specified is exhausted or the coupons life expires.

For example a $50 store credit voucher used at checkout for a $30 purchase will allow for a future purchase of $20 or until the total value expires or is exhausted. Customers can also buy products worth more than the remaining store credit and pay the difference at checkout.

Store Credit includes a handy utility for generating and emailing a credit coupon to a customer by entering their email address and the amount.
