Last year I started dropping by a Half Price Books store during my lunch hour near where I worked. You never know what treasures you will find there. This year I am working from home so I was overjoyed today to discover a store near where I live.
This particular store sold paperbacks at half the cover price. I bought a copy of Who is Ayn Rand? by Nathaniel Branden for 30 cents -- half of the 1967 cover price of 60 cents. It would have cost me $22+ to purchase it through Amazon.com as an out of print book. A successful hunt.
