Once you figure out the shop, it isn't difficult. The reporting can be, if the system isn't cooperating. And you can only do ONE report at a time. Once you start it, you're locked into that report until it's done, you can't get out and do all the others until that one is fixed... so if you do a number of shops, you can be in trouble with the reporting... And I will say, if you did the last round, where all the cards were set to be declined, these are better

Not nearly as embarrassing!
