I got King's IT for 10p, beat that, lol. That was at a fair stall.
I only really go to Borders, but if I'm at the mall then I go to Waterstones.
I got about 20 books around Christmas time, so got those to keep me going.
When I do go book shopping, usually come away with 6+, I'm a slow reader, so got two book piles in my bedroom of books to read.
I need to buy about 5-10 a month for my studies
What are you studying?
