Does DSLR's go on Sale for Thanksgiving? - 1

Does DSLR's go on sale for Black Friday? I want to buy an entry level dslr. Maybe a Canon/Nikon.
t3i or 500d. I'm taking a trip soon to up north. Is there a website that specializes in DSLR's?

I guess it's too easy to look at the circulars and check online or even pick up the phone and do something as simplistic as call the stores.
