{2} - At Mr. Carlson's request, the teacher leads anyone choosing to follow outside of the wand shop. "He's not really a wand merchant, more of a pawn shop owner. He usually carries a quantity of new wands."
The group arrives at the new store. The merchant happily greets the chaperone, but regretfully states that most of his wands have already been purchased, and he won't be getting a new shipment in for a few months. {1} - He only has two second-hand wands. They look very well used, and weren't top-tier when new.
"Hmm, it was worth a try. Let's see," He pulls out a leaflet listing the stores in the mall ".. I don't think you can buy wands from anyone else here legally, and couldn't begin to point you to shady dealers," he spends a few seconds looking at his thumb, which is over only a single store near the south-west corner, on the bottom floor, the leaflet angled such that it can easily be seen, "not that I would advise trying such a thing in the first place. Can't be too careful with the quality of your children's first wand .. This is the only major market for magical goods in the state, and school would have started by the time I finished cutting through the red-tape to take us to the Massachusetts community." He looks to the muggles' parents before continuing, "Mail-order wands aren't a good plan at all, trust me there. I'll see about leveraging the school to lower their prices for students, but that will take time. I don't think there's much else I can do." He shrugs slightly.
Tyson's shopkeeper gives him a hard look when he asks about getting magical foci tattooed on his hands.
"No, kid. Ignoring the fact that you're still growing, which would ruin them, I have a friend who had the same idea. He goes by 'No-Hand Ronny' these days."
