I used to feel like that when you could get the official rate if you paid all of your taxes and worked in blanco. Now that people earning high salaries en blanco and paying every centavo of their taxes can't buy enough dollars for a cell phone I've come to recognize that the official rate is a complete fantasy rate. If nobody can buy dollars at the price, then that is not the price of the dollars and it is unreasonable to expect the owners to accept it.
To answer the OP's cuestion. I wire my money from my US account to my landlords Argentine account where, after accounting for the source of the funds (rent) and paying taxes, he has the money in dollars.
