Ramping up efforts to compete with Amazon Prime, Walmart has expanded the company’s grocery delivery service to more than 1,400 stores across the United States. It originally launched as a pilot program in Houston, Miami, Salt Lake City and Tampa.

The service costs $98 for an entire year of service or $12.95 for monthly service. When enrolled, customers can make unlimited Grocery Delivery orders without paying an additional delivery fee. Walmart is offering a 15-day trial of the service, which auto-charges you at the end of the trial to continue the service.

Of course, if you don’t order groceries frequently, you also have the option of paying a delivery fee instead of subscribing to Delivery Unlimited. If your local Walmart store doesn’t offer grocery delivery yet, you will have to wait until the company expands the service into your area in order to sign up for Delivery Unlimited.

Walmart is planning on pushing out the service to more than 1,600 stores before the end of the year. That would cover more than 50 percent of the United States. If you prefer to just pick up grocery items yourself, Walmart’s Grocery Pickup service is available in more than 3,000 stores across the country.

More grocery stores across the nation are offering pickup options for customers. Check your local stores for their services. Alternatively, you can also look as a service like Prime Pantry to get groceries delivered, which charges Prime customers a flat $5.99 shipping fee per order.
