As Kunur Patel writes in Advertising Age: “Since few shoppers can wait for Amazon to ship their gallon of milk, smart phone usage in grocery stores is an entirely different beast than in big-box and electronic retailers, where the ‘scan and scram’ phenomenon of price comparing runs rampant. Consumers aren’t price checking against the Piggly Wiggly down the street the way they compare the values at Target vs. Best Buy, so mobile apps are popping up as tools for shoppers to find manufacturer deals and make lists as they trawl the supermarket aisles.

Phones are used more for shopping for entertainment products, restaurants, and consumer electronics.”
