i have just been messed around by a developer and have paid him for something that doesnt work. this is what i need: i need a plugin for woocommerce that will not allow you to check out unless you have applied a coupon. if no coupon has been applied it must add a fee of £5 to the order. to recap: the plugin must force a coupon and explain that a £5 charge has been added to total due to missing coupon, im in desperate need of this, my sale is in a few hours. i can provide a staging dev site so you can create it with my other plugins and theme in mind. i have the other devs plugin that you could look at also.
