Walmart
In July 2004, in what became a controversial business move, American retail giant Walmart took over Supermercados Amigo. Claims of unfair competition and monopoly were instantly made by smaller supermarkets, because Amigo would be backed by the strong assets of Walmart. As part of the agreement made in order for the purchase to take place, various supermarket locations had to be closed (specifically if there was a Walmart or Sam's Club nearby). The closed Amigos became part of a new (at the time) supermarkets companys known as "SuperMax" and "Pitusa Markets"
The structure of the supermarkets themselves was not changed because of the purchase, the only exception being that now customers may pay for their purchases with their respective Sam's Club or Walmart Credit Cards.
