I'm a newbie in magento. I'm trying to add the Shopping Cart price rule "Buy X Get Y".
In my case, I want to let the user buy x number of Products from Product A and the user will receive the same amount of Products from Product B for free.
This can be done by adding a rule for each value of x, but that is meaningless.
Is there another way I can achieve this? Something like a loop?
Thanks in advance
