How can I make the following rule?
Product: T.Shirts comes in 5 colours and in 5 sizes. It is set up as a configurable product.
Buy one for 120.- Buy any 2 for 200.-
With buying 2, I mean not just buying 2 in color red and both in size Large. It should also work when you buy 1 red/large, 1 blue/small etc.
Is there a way to set it up without buying an extension? What I did so far:
I have added all SKUs, both for the parent and the child products, as a shipping cart rule. When I activate the rule, go and choose 2 items and press "buy", then the page stacks and never proceeds to the basket. When I deactivate the rule, then the page is working fine again.
