I come from Australia, and at festivals we have what we call showbags, where people can pay money, and take home a bag full of goodies. It saves time on clicking on multiple items, plus it would look cute, to open up a goodie bag, and open the items like that. Or we could have a random grab bag, where we pay sp for it, open it up, and it could be anything inside. I think this would be exciting to have as a feature of the Merch stall. If it's too late for it now in the event, perhaps for the next event we could have something like this? :)
