Amazon is best known as an online retailer, but a new report from The Wall Street Journal indicates that the company is looking to expand its brick-and-mortar presence with new grocery stores for Amazon Fresh subscribers.

The stores would be an expansion of Amazon's existing grocery delivery service

The grocery stores — which the company has been rumored to be working on for over a year —would be an expansion of Amazon’s existing Fresh grocery delivery service. The stores would be exclusive to Fresh customers, which is available for Prime members in select cities at a monthly fee of $15 on top of the annual $99 Prime cost. In addition the the actual grocery stores, Amazon is also reportedly planning drive-in curbside locations where Amazon Fresh customers can pick up their online deliveries.

The Amazon Fresh stores wouldn't be Amazon’s first foray into brick-and-mortar retail, either. The company has had several pop-up locations in the past, and opened its first physical Amazon Books bookstore in Seattle in 2015, with more Amazon Books locations planned for Chicago and Portland later this year. Additionally, more stores for the Amazon’s other products, like the Amazon Echo and Kindle, could be on the way, with the Journal reporting that the company is "considering other brick-and-mortar store concepts, including a showcase for its consumer devices," in the future.
