Where can I get good exchange rate for mexican pesos? In NY? How far is the buying price off "actual" price?

I've got a whole load of mexican pesos I need to exchange. I am in Europe at the moment where buying rate is only about 75% of the rate you find on the websites. Where can I go to get a better rate? Considered going to NY. Brazil, Dominican Republic, even Mexico itself also possibilities.Where can I get good exchange rate for mexican pesos? In NY? How far is the buying price off %26quot;actual%26quot; price?exchange rates change daily and are worldwide. the question is not where to exchange them, but WHEN. holding on doesn't necesarily mean a good payoff later. just exchange them and invest the money in a high yield or a cd.
