walmarttogoThose living in Denver can now shop for groceries online and pick them up outside of a Walmart store.

Walmart To Go, the home delivery service operated by Walmart, first arrived in Denver this past October. Now, the store is testing a new service that lets people order online and then pickup purchased items at a designated area outside one of the 11 Denver-area Walmarts.

Walmart has been testing its grocery delivery service in San Jose, San Francisco since 2011, TechCrunch notes. In addition, the company also offers same-day delivery of merchandise in Northern Virginia, Philadelphia, Minneapolis, San Jose and San Francisco.

The retail giant is competing with the likes of Google, Instacart, Safeway and most certainly Amazon in the grocery delivery space. Amazon Fresh arrived in San Francisco this past December, and had already been operating in Seattle and Los Angeles.

Walmart’s Denver expansion is another example of the company’s effort to surpass Amazon in the e-commerce arena. The Arkansas retailer has invested heavily in its online shopping business for the past few years and it doesn’t appear to be slowing down anytime soon. The two companies have actually sparred off and on in recent history, starting all the way back in 1998, when Walmart sued Amazon for stealing trade secrets.
