How can I add functionality for buy 2 or 5 get 1 specific product free.
Is there any setting or cart price rule or extension to solve this requirement?
You can get reference from below link, might be same requirements of you in below answer link,
I'm also wondering that, I tried the "Buy 2 specific products and get one specific product free" guide but not working for me. I want to do "buy one specific product and get one specific product for free" offer. Tried many different ways, none of them worked.
