Good morning
probably I have not explained well and I apologize for my bad English.
I know i can choose what products coupons are applied to. But this does not solve the problem I found.
I have product X which belongs to the Y collection.
One day I make a special offer on X, discounting it directly from the control panel.
Just in that period, however, I have coupons that also apply to the Y collection (eg. Spring discount -10% on your cart subtotal).
The customer who will place the order and insert the coupons will be discounted with X twice: 1- from the direct discount 2- from the use of the coupons.
What I ask is that I can choose to disable coupons on all already discounted products.
Customer buys 10 products
6 belong to the Y collection of which 1 is X
Inserts Spring Discount
the total will be
4 products not discounted
5 products with the Spring Discount
1 product (X) with only the basic discount (without Spring Discount)
So you can comply with the best classic statement: Promotion not combinable with other offers.
