When I go grocery shopping, I now bring a calculator with me. It has become a necessity already because most of the time, I find myself over the budget while the items are being run against the barcode scanner. I have this weird habit of paying for everything I got, even if it is over my budget. I don’t take back some items to cut back on the costs. It’s just one of my quirks. So instead of putting myself on the spot at the cash register, I am now calculating everything while prowling the aisles of the grocery store.
