@JAN - No, I can't go through Western Union because my UK bank account was closed last year. I get paid in PayPal and just use NUBI to send it to my Arg bank account. However, NUBI works on the official rate. It was fine until about three months ago, but now it's a disaster to be getting the official rate.
For example, I sent $1,000 last week and got around 65,000 pesos. If I was getting close to the Blue I would have had over 100,000 pesos. That's a massive difference that it burns me that I am not getting it.
