2 coupon issues/questions:
a) I have a limit on one coupon per person, but if they go in and order 2 of the same product, the system is applying the coupon code to both products. So rather than just offering a %age off a certain product, I'm having to calculate it and put it as $ off the order, with a unique discount code for every single item, which means they can't then add variations without it mucking up the total. Can 1 coupon per person be limited so it does not apply the coupon twice in the one order?
b) Is there a way to cap the amount people can claim? I'd like to offer 50% off xyz capped at $100 total discount, so whether an item is $50 or $200 they get 50% off but if they order something that is $300 then they only get the $100.
