NEW YORK (MainStreet)—A recent survey by HelloFresh found 52% of Americans spend more than two hours a week at the grocery store and 30% spend more than three hours roaming the aisles. Add that up and you might spend between 104 and 156 hours a year shopping for food. And if the time drain isn't bad enough, the study also found one in three Americans overspend by at least $50 a week on groceries –$2,600 a year. There's a solution to both problems and it's on your smartphone. These free websites and applications simplify shopping, cut down on coupon hunting, and make sure you don't overspend.
