Wal-Marts selections are adequate as you say, but I prefer a more than ''adequate'' selection. Wal-Mart is a destroyer of choice, but hey!, more power to them, you know?
As I said, it depends on where you live. ''Choice'' has already been destroyed in my city & it wasn't by Wal-Mart. We don't have a Wal-Mart SuperCenter. Choice was destroyed by a strong regional chain (that itself has been consolidated into an even larger regional chain) that has snuffed out a number of smaller competitors. That chain effectively owns the grocery business in my not-small town. I drive approx. 20 miles to shop at a SuperCenter, specifically, to buy items that the local chain does not offer. ''Adequate'' is a relative term; I consider the local stores ''inadequate.'' The recent addition of a SuperCenter in a neighboring town has expanded my choice & offers the items that I consider ''adequate'' (that is, everything I want to purchase). ''Boutique'' grocery shopping is not an option in my locale & never was. If it's boutique groceries I want, I would need to travel 90 miles.
