Apparently, there are sites that leak Black Friday ads - some "leaked" by the retailers and some hijacked.
If you are interested,
here is the article. And some of the sites:
http://www.blackfriday2010.com/
http://bfads.net/
http://www.fatwallet.com/best-early-black-friday-deals/
http://dealnews.com/black-friday.html
Doesn't mean a whole lot to me as I avoid these places on that day like the plague, but I thought it might be helpful info to others.
