The following was posted to the Canadian board from the manager of the Eaton Centre Store in Toronto. I would assume the same is true of the US stores (was last year as we were in Ohio) and most of Canada does not do BF deals...
"The TEC store will be opening at 6 a.m., and offering an additional 20% off your entire purchase, even on top of the big deals, until 10 a.m."
Hope that helps!
