The Wal-Mart here is really pretty decent. Good selection. (at least for the stuff I'm looking for). And they have Greek Yogurt.
I LOVE that stuff!!! It gets crowded on the weekends though. And when the college students return in the fall.
Target is across town. And I don't really like the store that much. It's attached to the mall.
It's always really busy and they are never well stocked.
