Where can I get a clutch purse?

Im looking for them for gifts, and maybe one for me. Im looking for a rectangular, strapless purse, not too beaded, not little-girlish.
I looked in on ebay, in Macys (good grief), in Burlington Coat factory, Filenes basement and TJ Maxx. (I walked down Broadway on my way to the subway).

Anyone know where I can find one?
