Hello, I am using discount coupon codes contribution without any issue for order totals greater than zero. We have a requirement where we can allow free products too. But, if I give a coupon with 100% discount and if a user use this coupon for 1 product and if the order total is zero with the coupon, it is giving error during checkout that order total cannot be zero. how to allow 100% discount and skip payment in case of 0 order total? Thanks, Karuna.
