Last summer on a shopping trip with my Mom I found the greatest thrifty buy ever. We went to a small town about an hour north of where we live that has an amazing lavender farm and a ton of artsy shops and antique shops.
While browsing through one of the shops, the store owner told us that there was a shelf at the back where everything was a dollar. That peeked my interest so I went and took a look.
I found about a hundred old books. For a dollar each!
