You probably already get half the things in your house from Amazon, whether it's diapers or holiday gifts. But according to the Wall Street Journal, the company isn't just satisfied with that—it now wants to be your neighborhood grocery store, too.

Amazon is reportedly set to expand its Amazon Fresh grocery delivery service by making it more local. The idea, which is under the codename Project Como, is to build small stores that would act more like convenience stores, selling perishable goods like milk, meat, fruit, and vegetables. While there, you could access your Amazon account to order other groceries for same-day delivery. They're also working on drive-up grocery stores, where you could show up with your car, have your license plate read, and have your grocery order delivered to your car.

The idea is apparently to compete with companies like Walmart, which sell billions of dollars worth of food and drinks every year. Walmart has been trying to beef up its online sales and free shipping to compete with Amazon, and it looks like Amazon is working on a grocery strategy to beat Walmart at what it does best. Walmart, for example, is already planning curbside pickup at thousands of its stores.

After being tested in Seattle for years and slowly expanding across the country, Amazon Fresh is already going through a shakeup to make it more affordable, and thus more popular. The service used to have a whopping $299 annual fee, but now will only be $15 a month on top of the $99 annual Amazon Prime subscription. (You can sign up using a 30-day free trial to test it out.) With this service, it's competing with companies like FreshDirect and Peapod for your grocery-delivery dollars.

Amazon declined to comment to the Wall Street Journal about its plans, but it might not be long before you can head to an Amazon brick-and-mortar grocery store. According to GeekWire, the company has been building something mysterious in Seattle, and it looks like it will be the company's first drive-up destination.
