Walmart shoppers living in major cities around the country will be able to get their groceries delivered to their door by the end of this year as the retailer expands a service that could give it a leg up in its ongoing battle with ecommerce giant Amazon.

Tom Ward, vice president of digital operations for Walmart said, "we will be able to deliver fresh groceries to the doorsteps of millions of Americans."

Shoppers can make their purchases on the grocery section of Walmart's website or through the Walmart Grocery app.  A minimum purchase of $30 is required, and customers will pay $9.95 delivery fee.  Here's more from USA Today.
