Jim, Dan -- We could help out, y'know. We do Thanksgiving around mid-October (2nd Monday thereof), that being the harvest festival, for climatic/ecological reasons. Far as I know, nobody flips out and goes shopping on the preceding Saturday or following Tuesday. So, you're more than welcome to celebrate then (I know it's Columbus Day, chez vous, but really...)
The "Black Friday" thing seems to be creeping north of the 49th parallel: partly, it's US retailers advertising their wares to Canajans living close to the border (i.e., most of us), partly, it's the Seeping Cultural Hegemoney (sic, deliberately) Thing, with Canadian retailers following the lead of their reference points further south, flogging stuff that no-one needs.
I did notice that bicycle retailers joined the rush, such as the Bike Touring News folks in Boise, and Arkel in Sherbrooke.
PS: Interesting flip engineered by the advertising industry, isn't it? To think that "Black Friday" once referred to the start of the catastrophic depression in 1929...
