Today Exchanged $1 at 65 AR Pesos
At Florida the best deal I got today was 65 AR Pesos to the US$ The forum front page lists today's blue rate at 76.25, I didn't find anything near that. Most where offering between 59 and 65.
Credit Card - Cash- ATM- Etc.
Let me give some numbers:
In Florida cash exchange I got $1US = 65 AR Pesos today.
Using my credit card (I do not get charged any foreign exchange fees or so): $1US = 59.53 AR Pesos.
Using my ATM (my bank refunds ATM Fees): $1US = 59.47 AR Pesos.
Be carefull with ATM fees, they charged me 625 AR pesos (US$ 10.51) which my bank refunded. So if you use ATM it can get pricey, also I do not know what the withdrawal limit is?
As far as I can conclude, cash will give you about 10% or so more value, not so much of a big deal. I thought the blue rate was around AR75+ which would make it really beneficial. However, at 10% I do use my credit card when convenient. Also as far as a cash discount, sure any country, even in the US, when you pay cash vs. Credit card you can get a discount, for example no sales tax, etc.
One more note on credit cards: Foreigners as of now do not pay Hotel Taxes when they pay with a foreign credit card and have a non Argentinean passport. So in that case it is actually beneficial to pay with credit card, because the Hotel tourist tax is around 21% or so added to the room fee.
Good Luck.
