Shopping Cart With Calculator Built in on Handle

Adding calculators to shopping carts will be beneficial to the shopper, possibly encouraging them to shop where the calculators are. The calculator can be built in along the length of a wider handle. The calculator can have a flip top over it that can be pulled toward the shopper and left to hang down in front while the calculator is being used. Then the top can be flipped back up after use to keep foreign matter out of the calculator area. There would be only a need for the basic calculations of addition, subtraction, multiplication and division.
