Shopping in big box stores can give you a headache if you just want to run in and pick up a couple of things without spending the day navigating those long corridors looking for items.

To help shoppers make their way through the store, retailers like Home Depot, Walgreens and Wal-Mart have added a new function to their apps that let you search for an item in the store and locate the aisle number for the item.

USA Today has more: “In a store, ‘I can talk to an associate, but I can’t search for a two-sided tape,’ says Gibu Thomas, Walmart head of mobile and digital. ‘Mobile brings the (online store) to the store.’ Within two weeks of Walmart’s May launch of the ‘In-Store’ mode in its app, about 15% of page views were from shoppers in stores.”
