Smart Coupons for WooCommerce

When an offer has multiple “Coupon” choices, for example if I am giving away a free t-shirt when they purchase a specific item and the user has to choose from sizes: Large, Medium, Small, it would be helpful to have an option to require the user to choose a coupon before they can checkout.

The requirement would have to relate to the group of coupons involved.

Unfortunately, there seems to be a percentage of customers who fail to understand that they have to click on a coupon to choose which free item they want. Then the order requires a followup contact with the user.
