It seems that the high cost of text books is here to stay. While our shop doesn't stock text books, it's sometimes good to check out online sources. Amazon is running a special on prime for students, in fact it's free! We've found that they are a good source for new and used text books, and if you're able to use prime, there's a good chance you'll get them quick!
If you want to check prices on books, not just text books, there's a great online site that we use - bookfinder.com Ideally you have the ISBN available and then do a search. The site checks many online sources for the book so you can find the one that might serve your needs best!
