We're in Bariloche, on an eight month trip and long out of US dollars in our pockets. Getting killed by the ATM and bank fees. In Buenos Aires, I was able to wire funds through Xoom at a good rate. No Xoom here and Western Union goes by the official rate. Do I jump over to Chile? Would appreciate some advice from someone who has figured out how to obtain dollars or a better exchange rate on a wire transfer. Thanks!
