Can anyone help me to know how to set up this kind of promotion for the store?
1/if I buy 10 items of any products belonging to a specific category I will get 1 free B Product
This should work with 20 items : 2 free products: but I just get 1 after all
2/Bonus free product but I want customer to choose between different selections of bonus
I am using CS Cart ver 2.1.4
Thanks
