i also go to school in new york (nyc) and i know for a fact that you can get some killer bongs/pieces/bowls on the streets for mad cheap. my suggestion (if you are anywhere near the city), save yourself the shipping cost and overpriced hype and buy a nice bong on the streets (union square is a good place to look, so is canal street). Its not uncommon to find a decent bong for a max of $10-$15 and most of the time you can work them down. I would not recommend headshops in the city, they are far too expensive. i got a pretty small bowl from a headshop in midtown for $65, biggest waste of money.

and also you might want to look a little deeper into your school rules, im fairly certain that it would be illegal to have a bong on campus but i could be wrong.

happy toking
