The best rate around Santiago seems to be at the licensed exchange house at Farmacia Santa Lucia, Las Carreras esq. Sabana Larga in Centro Ciudad. They pay 49.60 pesos to the USA dollar. Warn everybody you know to about Cambio Globo at the airports. I call them Cambio Robo and people laugh as if it´s the first time they heard it, yesterday offering 40.82 pesos to the dollar. I guess the pharmacy has to exchange a lot of pesos for dollars to pay invoices, and they´d rather buy them at 49.60 than at the bank for 49.73.
