Input: TL;DR at the bottom

So, I live in close proximity to a comic shop and I and my friends love comics, they live far away so they tell their order, give me the money sometimes before or after, I have a friend who owes me about 39.75$, which is a decent amount at our age.

He's been paying recently, but he still knows as I've brought it up SO many times and he hasn't paid me, so WIBTA if I kept his order of 49$ and the money he already paid me, until he pays me back, I've considered it so many times, just don't know if that be a dick move. 

My other two friends think it's a good idea because he owes them as well. 

TL;DR Friend owes me money, so I consider holding is 50$ and 50$ order until he pays me back. WIBTA?

SO, WIBTA for keeping the books and the money until he pays me back the 40$?

holding my friend's stuff until he paid me back
