When I made the previous post (about twenty minutes ago), the WU page showed an exchange rate of just under $50 Argentine pesos to one dollar, and it clearly included the words "Argentine peso." I copied and pasted that data in my post.
Apparently, Rich and Aztangogirl saw those numbers.
I then reloaded the page and the word Argentine changed to Philippine. I closed the page, loaded a new one and tried again.
I got the current (and correct) exchange rate for a transfer of USD to ARS of $83.84 to one.
I then edited my previous post to show that figure.
