Google Now is powerful, it is very powerful and the power keeps growing (scary ehh?). Google Now is capable of detecting when you are going to a store, such as Home Depot and when you get there, it may show you information relevant to the store.
This includes showing you the indoor map of the store, the ability to search the store's local inventory, their return policy, and even see their special deals for the week. You can of course also see their web site.
But how cool is that?
Here is a photo from Google's Erin Pierce showing off this feature.
She posted this on Google+ and called it "brilliant." Indeed.
