I have my coupon set as a “fixed product discount” to a specific product and that they must purchase 2 to get the discount, however, it’s every 2 that they purchase they receive the discount. So if there are 3 in the cart, the discount is only applied to 2/3 products in the cart, but will be applied to all when there is 4,6 8, etc. in the cart. Does this make sense? How can I implement this?
