provide a maximum discount amount when creating any coupons
When a customer uses a product coupon they can change the quantity of the product being ordered in the shopping cart and get more of a discount. For example, if I was the merchant offering a coupon code for 1 free product. The customer would place that product in their cart and change the quantity to 2 or more, then enter the coupon code and get as many of that product they wanted to for free. This is a HUGE flaw in the 1SC coupon system and needs to be addressed.
