I didn't actually buy a book from them, but I was seriously considering buying from them because of the cheap price (and no shipping!). Something didn't feel right, so I did a google search of reviews for the site and came up with this:
http://www.la.bbb.org/Business-Report/Textbookw-*******
They are based in California, and the BBB has given them an F rating in which they conclude:
"We strongly question the company's reliability for reasons such as that they have failed to respond to complaints, their advertising is grossly misleading, they are not in compliance with the law's licensing or registration requirements, their complaints contain especially serious allegations, or the company's industry is known for its fraudulent business practices."
In case you're wondering, the F rating is the lowest rating.
I hope I saved somebody some grief. I'm glad I took the time to look them up. I guess just remember that if it seems too good to be true, then it probably is. Good luck in your college textbook search. :)
