Walmart is going head-on against Amazon in a race to deliver merchandise to online shoppers.
On Tuesday Walmart rolled out its next-day delivery service in Phoenix and Las Vegas.
The company plans to make the service available to 75 percent of the country by the end of the year.
Walmart’s delivery applies to more than 200,000 items but customers must spend at least $35.
The move follows Amazon’s decision last month to offer free next day shipping to its Prime members.
Some analysts say customers expecting one day shipping is becoming the norm.
However some analysts and investors are concerned the cost of setting up that service could drive down stock and profit margins.
