Set as describe but the it’s only partly working.
A = 17€
B = 13€
C = 13€
D = 20€
Your usage rules give me this result: Discount is 30€ (A + B) but it should be the cheapest two = 26€ (B + C). I actually need always the cheapest products (B + C) to be discounted 100%. I tried with different values and eery time it’s not taken the cheapest products for free.
