To be honest, don't buy loads of textbooks. Unless you actually need it to take and use in every lesson don't bother. We found that most were written by the lecturers and we never used them. When it comes to your assignments get to the library first and borrow them from the long loan (3 weeks) section. Any others not available reserve them. Then if it comes to your date being up and you can't renew them on-line as others have reserved them you just don't take them back, the fines are so stupidly low (except the short loan section) that the fines will cost you nothing compared to buying the books to start with!What is the best website to rent or buy college textbooks?
The best thing to do is to take the ISBN of the book you need and enter it on www.comparetextbooks.net; it will show you all of the prices for that book, so you will know for sure what is the cheapest place to buy it. And don't worry, they only allow reputable websites on there, so you won't have to worry about never receiving the book.What is the best website to rent or buy college textbooks?
Half.com is extremely reputable. It is a satellite website of Ebay. I've never had a problem with it. They are also the cheapest sellers I've ever found.
