Hi, I need to setup a discount coupon for 2 uses by 1 customer. I can see how this works if you sign up for an account, but I don't think it will work if someone goes down the route of checkout without sign up as the system will not know who is using the coupon to then restrict the number of uses.
So, I thought I could somehow be able to say disable the Discount Coupon in the order total if COWOA is used. so they would have to sign up to use the coupon.
Is this possible?

Thanks, Dan
