My daughter and I went to the bookstore to get her books for college. WOW!!! For 4 general classes and labs her textbook total was 485.00 and 3 of the 4 texts were used!!! I refuse to accept that as normal!! I wrote down all the ISBN#s, titles, editions and authors . I came home and spent the last 6 hours searching for alternative places to buy. I have one more book to buy and my total is right about $$ 220.00! They are not new but are the correct editions. I remember how, when I was in college and I bought books and barely used them then sold them for 1/3 the price at the end of the quarter. I did a textbook search and found: campusbooks.com, eCampus.com, didrecttextbooks.com, bookbyte.com, valorebooks.com, half.com but my favorite was bigwords.com. they compare all the sellers and list all the places to purchase. Be careful you are using the correct ISBN and then check the edition # to make sure you are ordering the right one. Good luck with your searching!!!
