I have been in the habit of hooking my boyfriend up with ebooks instead of text books, but sometimes he just wants a physical book. Checking out the University bookstore, Amazon, etc the price of used books is not as cheap as you would think. For example, buying a book new is $150, buying it used is $100. It makes no sense. So this is when I found a super cheap book store. It is called Abe Books.Please Log In to view this link! They ship all over the world, and sell from all over the world. So you can find the "international edition" (The low cost edition published for India) of the book, which is identical to the American version, for a third of the price. I ordered him 6 books from this site, costing him $100 TOTAL. Delivered! This was the cost of one of the books new from amazon. I have used this site for years, have no complaints. TOP TIP: If you make a purchase from Abe, sign up for SuperPoints, TopCashBack, etc, first and you will get money back on your purchase! Top cashback gives you 5% back and superpoints gives you 4% I think.
