How would I create a coupon for “get 50% off second item of equal or lesser value”?
The shopping cart I used to have allowed me to apply either a dollar amount or a percentage off and then I had a pull down choice of “apply discount to” 1) whole order, 2) each item, 3) shipping charge, 4) single product, 5) lowest priced item, 6) product category.
If you had something similar it would make your coupons even more flexible.
