Amazon knows you like its online review system so well that it just opened a physical shop around it.

The retail store--dubbed Amazon 4-Star--opens today in the trendy New York City neighborhood of SoHo, home to other well-known brands such as Apple, Warby Parker, and Casper. The store will only sell products with four-star ratings or higher on Amazon's e-commerce platform, including top sellers or new and trending items, according to a company blog post. Price tags are shown in digital displays and include two separate values--one regular price and a discounted price for Prime members. It is not clear if the amount will change dynamically to reflect price fluctuations on the online site. Amazon did not immediately reply to a request for comment.

It's also not clear how the company will pick the products it includes in this store, which would be helpful for vendors interested in getting placement. Obviously, an item would need to be highly rated and have a healthy number of user reviews. But it's not known whether Amazon factors in other criteria, like using its fulfillment services or being a  successful Prime Day seller.

The store features products sorted by different sections, including "Most-Wished-For," which are items frequently added to wish lists on Amazon; "Frequently Bought Together," which is exactly what the name suggests; "Trending Around NYC," for products bought by NYC-based customers; and "Amazon Exclusives." The company did not say how often it would change or revise these collections.

Jeff Bezos's company opened its first brick-and-mortar store, a bookstore dubbed Amazon Books, in 2015. Since then, the Seattle-based tech giant has expanded its physical footprint to include Amazon Go, a cashier-less grocery store; AmazonFresh Pickup; Amazon pop-up shops; Whole Foods Market; and now Amazon 4-Star.

It's unknown whether the company plans to open additional 4-Star shops in other markets. Likely, it'll test this launch, and depending on the reviews, plan accordingly.
