So I found a cool website the other day and had to tell you about it.
Basically it has a phone number you can call, and then enter the ISBN number of a book and it’ll tell you the price (new and used) on Amazon.com!
Some of the great uses for this would be: Checking prices of school books at the bookstore compared to online, Not spending impulsively when you browse at Borders, or Barnes and Noble, earning a little income buying books at garage sales (or dumpsters) and selling them online.
