They did last year, (and Flower & Garden booths did this year) but you do have to do it in one transaction at one booth. The tip from last year was if you want more than your 3 snacks at one location, have someone else get the things that you are not bundling into the QS credit. Ex: One person use the QS for the 3 snacks and someone else get your drink(s). Trying to do both just confused them.
