If I use this kind of price rule in Magento (126.96.36.199)
Buy X (1) get Y (1) for free (the step is 1) within a certain category - the rule only applies if customer puts 2 products with the same SKU (article number) in the cart. But that isn't the point of setting up the rule (to be valid within a certain category) is it?
I want the customer to be able to chose any kind of product as long as it is within the specific category, and when 2 is in the cart, the rule should apply.
Isn't this possible in Magento?
