I am new to the forum and my knowledge is limited. I have an online store and want to add to the payment page a Gift card payment. Where someone can put the card number in and it adjusts the price of the purchase. Ideally it would also track the amount left on the card but that can be done manually if needed. Currently the only options are coupons and there is nothing that would work for what we need. If anyone has any ideas I would greatly appreciate it.
