Walmart plans to invest $16.3 million in Nevada stores this year. The improvements and innovations are part of Walmart’s plan to invest $11 billion in stores nationwide. Sixteen Nevada stores will offer a grocery pickup option this year, and another six will begin delivering groceries. Five Nevada stores will see pickup towers put in place. The 16-foot-tall machines can fulfill a customer’s online order within a minute of their arrival. Fifteen stores will be seeing FAST unloaders — a device that automatically scans and sorts items unloaded from trucks . Another 15 stores will see autonomous floor scrubbers.
