RARE pics of Twilight Set

Hi, does anyone know where to get the twilight book collection from for a reasonable price and possibly in birmingham? because i keep searching and i can't find anywhere doing it for a price which isn't 50.00 for the collection. Do te have an idea o something that will help, because i have watched twilight, and i have heard that the libri are really good, hopefully the collection consists of
*twilight
*new moon
*eclipse
*breaking dawn
I would like to be able to at least read one of these since all i have heard is positive commenti on this collection.
