We are using Awocoupon with hikashop and we are using "Buy 2 Get 1" feature. We wanted to autoload the coupon when a customer added 3 products in the cart, which means the third cheapest one will be deducted.
I am aware about "Automatically add to cart 'Get Y' product" but that is not fit as per our requirement. We don't want to add the third product in the cart, but apply coupon automatically. Please let us know if there is any way to do this (even programmatically). We can customize the plugin files but need instructions from you.
