Coupon overwriting Cart/Catalog Price rule

[edgard_you]

Hi, 

I would like to know if it's possible that when I already have an active coupon (called A) and/or an active cart rule (called C), that a specific coupon (let's call him B) overwrites coupon A or cart rule C?

Thank You.

Hello @edgard_you,

Unfortunately NO.
Catalog price rules an cart price rules are independent.
The catalog rules are parsed separately via the price index and recalculated every night.
The final price of a product may or may not be influenced by a catalog rule.
The cart rules, don't care where the final price comes from. they just use it. So there is no way to determine if a catalog rule was applied to the price and disable it on the fly.
Also you cannot increase prices (not by default at least) by using the cart rules. You can only decrease them.
