We are trying to set up a promotion where if you buy 3 of a subset of products you get x% discount. It looked like we should be able to do this out of the box using sales rules conditions but I can;t get it to work.
Basically, I have set the rule conditions to be:
If ALL of these conditions are TRUE : If total quantity equals or greater than 3 for a subselection of items in cart matching ALL of these conditions: SKU is one of sku1,sku2,sku3
And the action to be:
Percent of product price discount 10%
When I add 3 of a the qualifying products (i.e. 1 of sku1 and 2 of sku2) I would expect to get a 10% discount but I'm still being charged full price.
Can anyone see what I'm doing wrong? This has been tested on our dev site and a clean Magento install with sample data.
