When adding a product There is a promo set to add another product and discount it 100% so its effectively a free gift.
This works without issue, however, when a coupon code for 10% is used as well it gives 10% off both products…even the free one
What is happening:
I add a $20 product and get a free $20 value product. I add a 10% coupon and I get $4 off
What should happen:
I add a $20 product and get a free $20 value product. I add a 10% coupon and I get $2 off (10% of the $20 I'm spending)
The bottom line:
Promos and coupons aren't really tied together in that manner, it's easy to start combining discount methods and ending up with undesired results.
ASPDNSF coupons doesn't understand that the free item is a promo item and shouldn't be counted in the coupon discount.
