Here in Spain, new books are quite expensive. For this reason, a lot of stores and market stalls run a book exchange system. Basically, you pay 2 Euro (around $3 or £1.75) for your first book. When you've read it, you take it back and pay 1 Euro for a new one. A group of us have the same reading tastes, and we pass our books around, and the last person to read the book takes it back and changes it, then the pass around starts again. It means that for every Euro we spend, we get to read 3 or 4 books. Are there book exchanges where you live? If you own a small business or raise funds for charity, it's worth considering starting your own book exchange. It's certainly a great way to read books cheaply.
