Argentinians are doing their best to escape the crushing inflation caused by rampant printing of the peso:

What they'll do is load up on purchases with their credit cards at the beginning of the month and then hope to pay at cheaper prices in USD terms at the end of the month.

Thus, the peso goes through mini-monthly cycles of boom and bust.

For example, had I attempted to exchange USD for pesos merely a week ago, I would've received 10% less pesos for my dollars, so it behooves me to time my rent payment accordingly.

When money breaks.
