Yeah, a VPN might resolve it. That 77,93 ARS to 1 USD rate is their ARS->USD rate though. I just checked and USD->ARS is currently 64,34 ARS to 1 USD. Quite a nasty spread, but still pretty good for us that have foreign accounts and don't want the lower official and interbank rates (and don't want to do the USD->USD, withdraw, exchange at cueva dance).
I want to figure out how to get that contado with liqui rate though. For those of us with accounts in the US it should be possible...
