Amazon unveiled the second location for its new brick-and-mortar retail concept that primarily stocks the most well-reviewed items from the company’s online retail platform.

The second Amazon 4-star store opens today in the Denver suburb of Lone Tree, Colo. The store in the Park Meadows shopping center sells items with a rating above four stars on Amazon.com, as well as new items and best-sellers.

The first location opened a little more than a month ago in New York City’s SoHo neighborhood. Items have digital price tags, which show the list price as well Amazon.com prices for Prime members, creating another enticement for joining the fast-shipping service.

The 4-star concept joins Amazon Books, Amazon Go, AmazonFresh Pickup, Amazon Pop-Up stores in malls, package pickup storefronts and of course Whole Foods Market in Amazon’s physical stores portfolio. Recent GeekWire research shows that Amazon is approaching close to 600 locations between these concepts.

In addition to starting up 4-star, Amazon has also been expanding Amazon Go in recent months. Five new locations of the cashier-less convenience concept in Seattle, Chicago and San Francisco have opened in the last few months, with more stores on the way.
