Wondering if you would consider adding a feature that would allow a merchant to create a discount code that would work for all products except certain ones.
For instance, I want the coupon to work on everything except perhaps a "custom" design product.
Currently the only way to make a coupon that will work for certain products, but not others, is to create one discount code for each product (except the ones that shouldn't accept it) and set the discount code the same for each instance, and make the discount amount flat rate match whatever is correct for that particular product.
That's a LOT of work that I don't have time to do. Please consider adding this feature.
