Step 1: Don't buy from the Bookstore
The first thing you’ll want to do is identify the book you will need. This can be done by finding the ISBN number. With this number you can look up your book almost anywhere. The first place you might want to look is on Amazon. From here you can shop around and compare prices. Check Ebay, and do a Google search for other online stores. You’ll quickly find that your book will be offered from these online retailers at a significantly lower price than your school does.
If you’re school doesn’t provide the ISBN number (sneaky sneaky) they’ve caught on to the game and are attempting to curve the dissenters. Not to worry, they no doubt provide the title of the text and hopefully the author and even better the cover image. If you’re looking up your books online and you still can’t find any of these things you may need to go to the school itself to get this information. Once you have found a little information on your textbooks you can then do some research on the internet. Amazon is a great resource for identifying your required textbooks. Once found you can then begin your shopping around.
