If you are a heavy online shopper, you probably search for a lot of things via Google. Since Google knows, what you are searching for it is taking that information and making it easier to find stuff you are interested in at local stores. A new feature has been added that will tell you when those items you searched for online are available in a store you are passing.
The feature would be triggered if you are out and a store you are near has the exact item that you had used Google to search for. The card for the feature could show multiple products if more than one item you have been looking at online is available at the location.
This is an interesting way for you to look for items, get all the details you need to make a buying decision, and then find the product locally. With Amazon and other retailers now charging sales tax, some of the benefits of ordering stuff online are disappearing and this app may help you find what you are looking for without paying shipping or waiting for the item to show up.
