If one has a US Citibank card, local Citi ATMs are the best bet... in terms of amount of $$$ they will dispense. The entire fee soap-opera depends on each customers individual agreement with Citi.

If you are a local (ie Argentina based) Citi Customer... then yes on both counts. You will get a higher amount of $$$ and, again, depending on the account plan you have, you will not be charged anything.

As an example... Im a local client of CitiGold and because of the agreement I have with them I get charged ZERO fees at all ATMs in Argentina... no matter what network or what Bank.
