I have a requirement for the following: "For every time a user adds 3 of a particular product from a certain category they should get a defined free gift automatically added"
So if a customer adds 10 of this product then they should receive 3 X Free Gift
I've taken a look at the extensions out there but they don't really seem to be overly clear at what they are offering. My question is, does anyone know how to achieve the outcome either manually or via an extension?
Thanks in advance
