Here is a site that lists most major retailers ads for the upcoming "Black Friday" sales, most are already up. Don't know if anyone has posted the link before, but it is nice to have a heads up. http://bfads.net/
Also be sure to check out the sales & events page at Chelsea Premium Outlets for black friday events happening at an outlet center near you! Each store will have its own promotion, but looks like there will be lots of extra reductions and additional discounts happening!
