A couple recent trips to the thrift store resulted in two gems:
Bird by Bird by Anne Lamott
Condition: The previous owner probably never opened it.
Price: Fifty cents
A good book for any library.
The Guernsey Literary and Potato Peel Pie Society by Mary Ann Shaffer and Annie Barrows
Condition: been read once
Price: One dollar
I tried to read this book several months ago when I checked it out from the library. I had been on the waiting list for two months then had two weeks with it before I had to return it. Those two weeks were busy, so I did not finish the book. Now I own it!
