Google Express is getting renamed to Google Shopping this week, so get used to seeing that new moniker online and in the app. The Shopping URL is already up and running, but the rebrand for the Express app hasn’t happened quite yet.
Google states that Shopping will have all of your favorite Express features, but will also include more products to shop, will offer a choice between delivery and pickup, and new Google-branded shopping cart icon for items that come with a Google guarantee, as well as deal recommendations based on your personal Google activity.
For the most part, the only big change is the name.
