After 8 years here, I can't still grasp some issues of the local economy.
I know that houses are priced in USD and the transaction is indeed in USD (usually using actual bills in a bag). I see that also some goods are priced in USD (like used Apple computers, cars etc.) but the transaction is ultimately carried out in pesos. However, it is my understanding that when buying from official channels, the conversion rate is the official one (this is why also prices in USD can be outrageously high), whereas on other markets (like a purchase between individuals) the blue exchange rate is applied.
I have a situation where a close friend asked for some goods from abroad, for which I paid in Euros. Now that I am ready to deliver the goods, this person wants to pay in pesos at the official rate, which is HALF the parallel one. I don't want to compromise the relationship, it was my understanding that it was implicit that in informal transactions the blue rate is the one to apply.
After all, if the goods were purchased directly abroad, using an Argentinian card, they would cost close to the blue price because of the various impuestos...
Am I off on this matter? I repeat, I don't want to compromise the relationship with the only friend I made here. I know they also travel abroad and make purchase while there. I assume they pay using an Argentinian card, or maybe they exchange 200 USD per month and then spend the bills in the US?
Anyway, I don't feel it is right to me if the exchange rate applied is half the actual value. I want to propose to get paid in USD, so that it is not my business whether they buy USD at 100 or 200.
The amount is 65 USD, so I would still need to give a change in return.
