Everything About Sending Money Out Of Argentina

Whats the best way to transfer $2500 from my dollar savings account in Argentina to the exterior to make a payment? Safe, fast and low cost.

I'm not in Argentina at the moment and I don't have a foreign account.
I did not quite understand what you need. You have a "caja de ahorros en USD" here in Argentina, and need to pay someone abroad. Maybe I can help you with that. Also, I'm in Capital Federal, where are you located?
