A spokesman confirmed the fact to CBS Miami. The location's proximity to the airport apparently plays a large part in booming sales as foreigners like to stock up on Walmart's cheap goods before heading home. From Chinese factories to a suburban Florida Walmart to South America. What a world.
Though, the Doral location's success isn't unique. According to a 2012 Miami Herald story, the Hialeah Gardens location was the top-producing Walmart in the country during that year.
Both locations are Supercenters, as will be the proposed Midtown location.
There are 13 Walmart or Walmart Supercenters serving Miami-Dade county's 2.591 million residents.
Though, to put that in prospective there's five Walmarts serving nearby Collier County's 330,000 residents, and 12 locations for Broward's 1.815 million residents. So the fact there's less Walmarts per capita here than in neighboring counties may play into the chain's individual store success in Miami-Dade.
