Add option for a store credit that can be drawn from for more than one purchase
Please add a feature to issue a "store credit" that can track the balance over multiple purchases. Many times my customers would rather have a credit toward a future purchase than a full refund. Alternatively, if I make a mistake on an order, I like to give people a credit as an apology and to encourage them to buy again. I have used coupon codes, but if the follow-up purchase is less than the original, I have to remember to issue another coupon with the new balance.
