Frugal Tip: Bring a Calculator Grocery Shopping
It might be the last place you think you need it, but a calculator is one of the handiest tools you can have at the grocery store. From calculating unit cost to comparing apples to oranges (literally), a calculator really helps determine the best bang for your buck.
Divide the total price by the number of ounces to compare different dry goods and brands of the same cereal. Easily add up the number of sheets of different paper towels or toilet paper (don’t forget the ply!). The list goes on and on.
So slip a calculator inside your reusable shopping bag today, and never be without it at the grocery store. One of my bags even has a little zipper pouch to keep it in.
