May be too late for some..but maybe not, I wanted to give you guys (in case you havent heard of it) a thumbs up for chegg.com, its an online bookstore that rents books for 25% of the actual cost of buying one. I just got a math book that was about $100+ for $14.95. They give you a date of when you should return it when the semester is over and you have the option of extending the date...And for the green folks for each book you rent, they plant a tree! awww....well at least that is what they say :-) Enjoy
