Just found a way how to bypass the ATM fee taking cash with foreign card.
With the foreign debit and credit card you can pay wherever you want, but extraction cash cost you a heavy fee, nearly 400 pesos and Max is 4000 peso, so thats 10%.
What I did was: register by todo pago and mercado libre, and download apps if you don't have them already.
Then I registered and approved my prepaid payoneer card by todo pago......Next enter into mercadolibre and make a request for money. The card then get debited by todo pago, in my case I did it with 4000 peso, and get credited by mercadolibre.......from where you can extract money with mercadolibre debitcard or via cashier.
Depending on how you have configured your incoming payments by mercadolibre, you can have it without any fees in 2 months, or for a few percent up till 6%, when u want it immediately........still better than 10% by atm......plus I think you can use bigger amounts......no idea what limit is, but for sure 10.000 I guess.
The dollar/peso conversion is the same as if you would make a purchase in the supermarket with your card!!!!
