I buy books online at ---> http://www.bol.com/ and locally at de Slegthe(used books store) and some other book stores.....
I try to keep away from the major chains when buying books... I can usually find some good reads at a second hand book store, and considering how much I read, I'm saving tons of money that way. I would go to the library but I like having a good collection @ home... read the same book 3 or 4 times at least....
