Spending Peso's overseas! You are kidding aren't you? I brought approx $200.00 back with me, and then had the bright idea of exchanging them here in Perth. Have so far tried 3 foreign exchange outlets plus 2 of the 4 major banks, just because I have always hated the words 'no, we don't do that'! As soon as they see a person with Argentine Pesos they pretty much pull up the drawbridge, yet fail to give an explanation of why they won't exchange them! If I ever get an explanation for this I'll be sure to post it here.
