I went to my local thrify shop today and picked up a couple of cheap books for $4, bargain! They are best sellers that would have cost me at least $30 if I bought new copies from a bookstore.
They can have some great stuff in thrif stores and it’s usually very reasonablly priced. I also like buying stuff from there because the stores are usually charities and I know my money is going to a good cause. I often donate some of my own things that I no longer need that other people may find useful. It’s a great system that recycles goods rather than throwing them out and wasting them.
