Google tell you when you go near a product you like
You’ve been looking for a product online, but haven’t gotten around to purchasing. With Google's latest release of the mobile app 'Google Now', when you’re out and about and near a store that carries that product, you might see Google Now showing you the product and price to remind you that you wanted it. The functionality is part of the app which provides the user with hints relating to the places they travel, such as train times when at a train station, the menu when you enter a restaurant or shop opening times when you enter a shop.
