Consider which books you really need to buy, as well – other than those your lecturers tell you to buy, you may well be able to get away with reading library copies, available to you for free all the time you are here in print, online, and in some cases available to download to your laptop, phone or tablet.
You get a student discount on Amazon while Blackwell offer up to 40% back on books bought from them (so long as they are still the latest edition and you keep the receipt!), so it pays to shop around and get the best price.
