What is a local head shop?

There is this place around my house that sells a few bongs but im not over 18 so they wont sell to me. I was like, dude it doesnt matter how old you are weed is weed. He told me his bongs were for tobacco. Yeah right.

How much does a decent bong go for.

If getting a bong is too much of a hassle ill just stick with joints and my friends bongs. It would be cool to have my own though.
