Grocery iQ is just one of the free mobile apps available for smart phones. These mobile grocery apps are a great way to store your grocery list and find the best prices. Most apps also download coupons to your local grocery card and can even scan a bar code.
I have to admit my husband and kids were the first to get me started with these savvy programs because they were all having so much fun scanning the pantry. Switching to a mobile grocery list is both frugal and green saving money and paper.
Other handy shopping apps include Foursquare and Out of Milk.
