Does the NAS sale encompass such a high % of items in stock, so that one would not buy anything now, or is the strategy more selective, to use it for “wants” or peripheral items?

I seemed to have lost out on a number of items this year due to selling out in my size. Of course, I never tried some of said items, so they might have been a bust. But when I'm looking at items now from time to time, I think, if it might be really good, I'd best try it now or it may be gone. This primarily for items I've had trouble finding so far but that I think might really fix a wardrobe hole or problem.

if I find an item “not too long” before NAS that has potential as a wardrobe essential/workhorse, would you order it and bear the temptation bo buy at full price ? and then use NAS as added value for other items? Or try to close your eyes until NAS?

I know there’s no one answer, because it overlaps discussions we've had on price points, sales, buy what you love and all that, and it's quite person-specific, but thought I’d see what various strategies NAS veterans have used to find the sweet spot between value vs. missing the occasional elusive great item that may sell out. I also didn't know if items tend to be re-stocked or stocked up for NAS and how intensive a shopper you need to be. I'm not very good at stalking day and night or being a "cyber Monday" type of shopper where you have to pounce within 24 hours to get a deal.

So answers don't have to be politically correct--I'm interested in various approaches.
