Minicuotas Ribeiro is a retail store like no other. It sells household products to low-income people in small-weekly-payments. People can buy furniture or electronics paying weekly, as little as one dollar.On December 2009 they opened their first major store in Buenos Aires. The challenge was to spread the news to local people about the arrival of Ribeiro and its tiny-payments system into town.The store is located right next to the city's largest metro station. Right there -where over 1 millon people go in and out every day- we had real street-musicians, with a special message on their signboards.
