It's been my sad experience that cuevas don't pay the newspaper rate.I got 833 on a small visa credit card transaction sunday 10/22. Very poor considering the blue rate closed at 1150/1200 on Friday. I will continue to exchange cash.
On Friday, the papers listed the dollar sell-value at $1150. However, two of my cuevas paid only $960, and a third one $l050. They were located in Cañitas, Palermo, and San Isidro.
If anyone has had better luck, please let me know where to go.
