In a store, we often encounter a situation where it is not entirely clear which of the packages is more profitable to choose. Washing powder weighing 1.8 kg. costs 199 rubles, and a pack of 4.5 kilograms is 479. The price of milk in containers of 0.9 and 1.4 liters is also difficult to compare. It is inconvenient to read on an ordinary calculator, which is why the "Buyer's Calculator" was created. You just drive in the weight, volume or quantity of the product that you want to compare and indicate its price, and then the calculator calculates everything for you (for you). Large and contrasting input fields allow even visually impaired people to use the program. Install the application and you will always know for sure whether a large bundle is really beneficial.
