Books, books, books... And I'm poor now

So far this month I bought 7 books. I have spent $1,056 (Argentine pesos) in 7 books. It's too much. I spent my savings on books. I want for books to be cheaper in this country, I don't have a stable job to be spending that kind of money! I feel so guilty right now! but the worst part is that I don't regret it!
