If a coupon code is entered and then the quantity changes in the shopping cart, the coupon gets applied more than once. I have the coupon set up under Conditions(Optional) as Total Amount. If I add a new item it comes in a full price, but if I change the quantity of the original item, the quantity updates at the discounted rate. You can test it on my site using webthank5.
This coupon is set up as:
Discount Value 5.00 $
Redemption Limit 5
Conditions (Optional) Total Amount
is greater than 6.00
Should I use other options than the ones above? I expected a total amount coupon to show up on its own line below the total rather than changing an item price.
