In our area, we have Wal-Mart and Safeway. I shop at Wal-Mart for staples, paper products, canned goods, cosmetics, personal items, and pet supplies. Then I head to Safeway to shop the perimeter of the store. That’s where the dairy products, produce, meat/seafood, lunch meat, etc. are found. Seldom go into the aisles.
You sound like a smart shopper...with a plan!
