Books: Where do you get them?

[RadioPatrol]

Do you buy them? From where?
Get them from the library?
Swap them?

I purchased 2 books at a thrift store. These 2 books are the first two in a trilogy. Now I need to find the third

in the last month I have spent $40 bucks @ the Oxon Hill Library buying used books a buck a piece .... some never checked out

The Fox Run shopping center in Calvert has Second Look Books. They trade books for store credit and have some new books. They will also special order books.
The Prince Frederick Library has a section of books ( used) that can be purchased for betweem $0.50 and 5.00.
Also strange as it sounds, the gift shop in Calvert memorial sells used books for $0.50 each.

I've been buying/trading books there since they opened.
