there is a save a lot a couple towns over from me and I have been curious (I like discount grocery stores) but alas I can't drive so I can only go where the bus goes.I go to Meijer often, there are many around here. Between that, Family Fare, Dollar General, and Aldi, since Save A Lot mostly closed up. I try to avoid Walmart, but some things are exclusive to them. I’ve been going to Dollar General since before it got all popular. I prefer the smaller stores, but I have to go to the bigger stores for things plant based or low in sodium.
I like aldi but I often won't go out of my way to go there. the vibes are just slightly off like an alien was given a very detailed description of what a grocery store was and decided to build one. I think it might be the size as the stores themselves tend to be smaller but the aisles and fridges and whatnot don't totally scale down with it. I like the prices though.
I also avoid walmart unless I need something I can't get anywhere else. the lighting is somehow more florescent there than other stores and their grocery aisles are too wide for my taste and their non grocery aisles are too thin for my taste and the inconsistency drives me up a wall. they have some products that I really like though so I will go sometimes.
I have not been to a dollar general in years but I used to go to get snacks there when I was at my previous transition program.
