MSN has a list posted of things you shouldn't buy new, here. Lists of 'shouldn't buys' usually end in used, but this ends in new, and is perfect for the money-strapped teen.

1. Books
For me, that's a given. I almost never buy books new, unless it's going to be forever before they are at the library, like something new, or if they are something I cannot wait for, like my favorite series books. Other than that, I am a frequent library-goer and Goodwill book shopper.
Do you buy books used?

2.DVDs and CDs
I wouldn't know, I don't really buy either. But the list has more explanation on most of these topics.
Would you buy media used, not just CDs and DVDs, but video games, computer programs, et cetera?

3. Little Kid's Toys
I have zero experience. Wait, no, that's not true. If I see something that I know my younger cousin would love, like a plush dog or something, I'll buy it if it's clean. But it has to be clean. I don't have any question for this one, feel free to comment if you would like.

4. Jewelry
I buy a lot of costume jewelry second-hand. I am not ever against buying something cute at a store in the mall, but if I see things like pop beads or new or unused jewelry at second-hand stores, I'll buy it.
Girls, do you buy necklaces or costume jewelry second hand? Do you buy for the prettiness or for the value?

5-10 are in the Extended Entry.
