Don't know how much of a leak it is and how much is just extra advertising, but here is the ad for BB's Black Friday sales, a couple noteworthy things, the 50" LED back lit t.v. for 199.99 and 100 bucks off iPads.
Galaxy S5 for a buck but then you get what you pay for.
Beats headphones for 80 bucks which I guess is about 50% off.
See the ad below.
