I am very lucky to live three miles from an intersection that includes Aldi, Dillon's, Wal Mart Neighborhood Market, and even a Braum's, so shopping at different stores for the best deals does not require much gas and travel time.
Typically I only shop at Dillon's or Aldi. I have not been that impressed with the Wal Mart Neighborhood Market. If I need to go to Wal Mart, I can go three miles north of my house and go to a full Wal Mart. If a Target were to move in within 3 miles of my house, I would be set!
Today I decide to take the time to shop at both Aldi and Dillon's to try and get the best prices. I did not do too bad. I think the only items I bought at Aldi where I would have paid less at Dillon's were a couple of 8oz bars of cheeses. I had a coupon for Kroger cheese, so I could have saved about 40 cents total. The coupon is good for a while, so I can still use it later.
