I'm a big fan of Black Friday (well, more of a spectator), but I've never really noticed any of the camera stores having anything special. It's more the big box stores (Circuit City may have some great deals as they're trying to stave off death) might have some photo equipment, or photo-related equipment (printers, memory cards, etc).
I'd check placed like Fry's, Best Buy, Circuit City, Walmart, Target, etc. to see if they have the random photo item in their list. They all sell varying degrees of photo equipment and you might find the hidden gold nugget in the madness.
I still think the surest bet is to look for things that improve your overall photo experience, such as memory, printers, ink, paper, frames, or Playstation 3.
