I've not been overly impressed wtih the Walmart Super Store prices. it's nice for a quick trip, but not for regular grocery shopping.
We recently started ordering food through Angel Food Ministries. www.angelfoodministries.com It's basically a whole sale food program (no program requirements) done as a ministry through local churches. You do not need to be a church member. Every month they put together a box of food for $30 that is supposed to feed a family of 4 for a week (at least dinners). If you purchase the regular box, then you're eligible to purchase the other boxes. I really like the fruit/veg box for $20. All my fruit was beautiful last month and my 17 month old loves fresh fruit. This month I also ordered a fajita kit, a steak box, and a mixed meat box. I'm getting all 5 boxes for about $115.
The newark Farmers Market on Kirkwood Highway, which is probably quite a hike for you btu something to keep in mind if you're down this way, has great prices on fruits and veg. We got blueberries, strawberries, a mango, fresh brussel sprouts, 6 large apples, and some chocolate (for mommy) abotu $12 today. Bananas are 25 cents per pound. The mango was 79 cents. They have an incredible variety of fruits available. You may be able to find a local year round farmers market.
