I live in Yankton, SD. It is a semi-rural community. I do most of my grocery shopping as well as general shopping at Wal-mart.
The other grocery options are Hy_Vee and convience stores. (Hy-vee is a midwestern grocery store). I buy all my food except produce at Walmart. Enviga green Tea (one of my weakness's, but an awesome calorie burner/energy drink) from the same Coke plant on the edge of town is $5.68 at Wal-mart. It is $7.79 at Hy-Vee. South Beach Diet frozen dinners (My lunches) are consistently $.5-$.75 cheaper at Walmart.
On average each trip I make to Walmart to buy groceries for a week for my lunches, I save nearly $10 on a purchase of only ~$40.
Ditto with clothes and electronics. To buy the exact same thing, I save $7.50 on my Hawaiin shirts.
Now I am just starting my MBA, but I don't need it to know that on my consumer level, Walmart is a good deal.
Just don't buy tools, plumbing supplies, or fresh produce there. Any boxed item I have not found cheaper elsewhere.
I normally stop at Walmart 4-5 times a week, so I can believe those stats.
