I took out money from the Banco Comafi on Cerrito near La Recova mid-week without any US$3 charges, but when I tried at the BNP Paribas on the corner of Av. Alvear and Cerrito, it tried to charge the Link fee no matter which network button that I selected (Banelco, Link, or otherwise). Is it possible that a ATM that uses both Banelco *and* Link enforces the Link fee, but banks that use only Banelco don't?
I'm afraid that I can't test this theory any more as we've returned to the US. Anyone else care to test it?
But I will add here, for anyone that reads this far, that PNC Bank in the US is one of those that doesn't have any charges of any kind for withdrawing money from ATMs in Argentina (and with the right account, refunds all 'foreign' transaction fees in the US). I literally made several hundred withdrawals over the last 10 months in Buenos Aires with *no* fees of any kind (percentage, fixed fee, transmission, anything), and the exchange rates always ran right at the mid-point of the buy/sell rates listed on places like Pagina12 for that day. I did hit both machine and daily limits at various times, but machine limits were easily avoided by making multiple withdrawals at the same time, which I tended to do anyway as I always took at something like 190 then 90 just to get the smaller bills. Highly recommended!
