Buy 3 get 1 free - how?

[jxm28788]

I have a product "ABC" in it's own group "XYZ", I want a "buy 3 get 1 free" offer on ABC.

I've then set a 'cart content' discount - based on qty, trigger 4, product group XYZ, reward 100% off extra...

but then can't select the XYZ group for the reward group...

I could get it to work by having a fixed reward, but the price of the product might change quite often so that would be a pain.

What I'm trying to do is set it so if they add 4 it will charge 4 and refund 1 - but if there is a way to do it so if they add 3 it will add another automatically with a zero value that will be even better.

Came across this myself.

Do not use % off extra product, as that is asking you to add another product to the list to add free: ie choose Product ABC (Group XYZ), get Product XXX (Group YYY) so that you can add a completely different product free.

To do what you want to do, you would be better to choose % off cheapest if they are all the same price. (Trigger 4)

[OOPS just noticed you are talking about V7, I'm in V8, how many times do I do that..... Hope that you have the same options .... otherwise V8 is a lot more flexible]
