The prices are pretty insane.
I have a niece with the same disease your son has and the marketing machines have her stacking up quite the bill trying to keep up with the crowd she wants to hang with. Luckily, she does do a really good job of taking care of what the people around her buy for her. I caught her complaining about her car being ~10 years old, which her parents fully paid for, the other day while putting a new battery in it and had to make a little bit of a corrective comment. The school parking lot being half filled with high priced vehicles doesn't help the issue.
Her younger sister, who is very financially conservative and had a part time summer job, told her if she didn't quit eating so much it wasn't going to matter what fancy brand she puts on her ass because no one was going to be looking at it anyways. Middle child for the win.
