Coupon Code parameters
I would like to have the option to choose the combination of coupon codes. For example, now the program allows you to combine or not combine. For example, 20% off on one coupon sent to certain individuals, $25 off $100 sent to another group, but both groups can have Free Shipping. No way to do this currently.
Maybe it looks like a check box on which offers to combine with as a drop box when adding new offers. If you want to adjust an old offer, you would have to go back and do so.
