"Walmart is the closest thing to "discount, no-frills" in the US, however it's 100% a facade. Their prices are realistically no better than chain grocery stores like Kroger, yet they do a very good job convincing poorer people that they are."

I don't have a Kroger nearby, but WM is far cheaper than any other grocery chain in my area. I go to WM for all nonperishable items and then a more expensive store for fruits/veggies/meats.
