We have a pretty urgent situation related to coupons. When the result of an applied coupon is a total of $0.00 (FREE) the checkout process is still sending people off to PayPal to make Payment.
The issue with this is that PayPal will not let you proceed (or go back even) so long as the total is $0.00. Not to mention the confusion caused to a customer by being asked for payment information on a free purchase.
The DNN platform is 5.06.03(45) and Cart version is 4.50.0
