I think any and all that "Black Friday" stuff is item-by-item.
I'm old enough to remember when Columbus Day sales were the secret beginning of Christmas shopping and featured psycho low prices on select items. If you knew what you wanted you could really make out and be ahead of the masses.
In other words, see a super price on something you've been needing and shopping for, then go buy it.
Go into the store, buy it, and leave.
What's the big deal with some of you people?
If you go shopping when you don't need anything, you're a dippy-doo. This has been true forever no matter what time of year.
Also, "shopping" doesn't mean "just buy". It means scouting out prices and comparing competing goods.
