I created Percent Cart Discount Coupon of 20%. I wanted this NOT to be used when there is any SALE PRODUCT in the cart or Any other plugin that I placed in Excluded Product Option. Even though I double checked my settings but this coupon is still applicable even when there is a sale product or excluded product in the cart. Please take a look and let me know how this can be fixed
I placed the code in functions.php file and nothing is changed. The coupon still applicable on Sale items and also on excluded products. I could provide you login details so that you can take a look and make necessary changes because I need it to work as soon as possible.
