Erm, I go to the library. It has loads of copies of nearly all core texts and you can withdraw them for a month at a time and just renew them online. I've had one book in my cupboard for half a year because I just keep renewing it online.

When I was doing my first course I think I bought one book (ANATOMY COULORING IN BOOK WOOO) and just did the rest in the library and on my current course I haven't bought one yet.
