Last Sunday I went to a grocery store with Rs. 1000 budget. The moment I entered the shop, I started doing mental accounting. That means the moment I picked up an item I started calculating the cost. After Rs. 850 I lost the interest to calculate. And understandably the final figure crossed Rs. 1000 mark. This has prompted me to find a solution to stop doing mental accounting and keep the purchase within the budget.
Attach a device to the bag which will show the price of a product when you drop it inside the bag. The more items you put in, the device will start showing the total amount of the purchase. In that way, you can always get to know how much you have spent.
The process would be really simple. Before dropping an item into the bag, you have to touch the barcode on that device. After that, the price of the product will flash on that device’s screen. Follow the same procedure for as many products you want to put inside the bag.
