if you are willing to travel to Calvert Co, over the bridge, go to the SPOT thrift shop. It is large and they have a lot of traffic so what you see today may be gone tomorrow...
All proceeds go to "fix" animals to stop reproduction. I have picked up a few great deals there! I have been to SMILE but they are not open a lot. I *think* SPOT is open Weds-Sunday, They are probably in the phone book.
Oh, they are in St Leonard, right at the light and down on the right next to the auction place. They have some neat stuff but pricey.
Hope it helps!
