Is there a way (without coding) or a plug-in with which I can define a attribute that holds a percentage per SKU which is then set to a price rule?
SKU % Price Special Price
1 5 100€ 95€
2 10 120€ 108€
3 20 120€ 96€
So if a user types in “BlackFriday” in the Checkout field for rabtes the user gehts the special prices like in my example.
