Yes- buying ten of anything at a time is good for someone with alot of family still home, not so good for any one else. Which is the whole idea- they can say but we have great sales, knowing most people are not going to do that buying.
My response to that almost guaranteed is not to buy whatever it is, period. The price cut is always substantial so that means unless it is something I really need (not going to happen) I just walk right on past.
I would do a co-op with someone if I had the option but I don’t have. I do garden and put up food.
We are going to need to know how to be conservative with buying, and certainly people in general are going to have to learn to live within their means (under their means, actually) or they are going to be in a world of hurt.
I grew up in a farm and whatever we raised or grew, we ate. Hated weeding that 2 acre garden and summer as a kid was not fun having to spend time picking, snapping, pealing, canning and preserving. But would love to have that garden space now. Funny what a difference 50 years will make!
