Trying to setup a coupon code that is valid for 1 use per DNN customer. Customers are required to create a DNN user account  prior to purchasing. As described in the manual, Setting the Max Uses to a number say of 1 should limit it so each DNN user can only use the coupon 1 time. What it actually does it limits the coupon to only be used 1 time period. So if Customer A (dnn user a) orders and checks out with the coupon, then Customer B (dnn user b) then goes and tries to use the same coupon, it says (coupon limit has been reached. Since this is a different DNN user it should allow Customer B to use the coupon one time as well.

Am I missing something on this should work?
