You guys have probably heard this a thousand times, but I really need to find some legitimate thrift shops that are cheap in NYC.

I'm looking for shops mostly in the Brooklyn area. Here are a couple of shops that I know of (not limited to Brooklyn, however):

Beacon's Closet
LoveDay 31
Housing Works

I'm saving up some money and I want to be extremely deliberate when shopping, now since money's tight.

So any suggestions?
