Write Prices On Grocery Purchases

When shopping for groceries and personal items, I write the price with a permanent marker discreetly on the packaging when I place it in the cart. This helps me make sure it rung up at the correct price at the register and it also helps me know how much I paid for the item when I run out and have to buy more. Writing down the price also helps me recognize a good deal if it is cheaper when I go to replace the item.
