I'm pretty tied to shopping at my regular old Kroger supermarket where selection is adequate and pricing is reasonable. My grocery list is organized by aisle and goes in order from the front door to checkout for that store. I can grab a basket and sprint through there pretty fast now on my way home from work.
Aldis I've never cared for. I don't know if it's just the local one but things were constantly moving, poorly organized and often out of stock. If I need one simple staple like eggs I will run through there but prefer not to.
Trader Joe's is nice for a treat, but not really good for filling your fridge & cupboards for the week.
Costco gives me mild anxiety, everything is too large but it is worth it for some things. A lot of things aren't that much cheaper than the supermarket but are higher quality. Comparison shopping there can be tricky though.
Walmart is a no-go for me. I have seen the people of Walmart, I don't care to see anymore
