Saving Time and Money

My mom just got in from grocery shopping and she is telling me how she enjoys it every time. There’s one thing my mom love when she shops at the grocery stores nowadays, barcode scanners! Not only that waiting time while falling in line at the cashier to pay has lessened, but also my mom could check unavailable prices immediately with the scanners installed on specific places inside the grocery store. With an arithmetic mind, she can calculate how much she will spend before paying her items –making her stick to her budget. She saves time and money at the same time.
