Amex Argentina has some special offers every Friday valid only for 24 hours ("Viernes Express" they call it). Today they are selling 100,000 MR points for 11,000 pesos. Considering that twice of thrice a year they offer a 1 on 1 conversion from MR to Avios and to Aerolíneas Plus, this means that, well used, you could buy 2 tickets from EZE to the USA or Europe in Economy for 11,000 pesos (630 USD). Great deal.
