Saw this elsewhere and thought this might interest people. In a nutshell, the Argentinian government have introduced a tourist peso exchange rate, designed to encourage tourists to spend in AR$ rather than USD. Except the scheme isn’t limited to physical purchases in ARG, so people outside of ARG have been setting AR$ as their preferred payment currency in PayPal and using it to get huge reductions in the cost of anything they buy, anywhere. Detail (copied from another site) below.
Of course, the jury is out on the legality/morality of taking advantage of this loophole, so caveat emptor.
Until recently, payments made in Argentina with foreign credit cards were changed at the official dollar exchange rate, which is AR$185.75 to the dollar at the time of writing. But on November 4, Argentina’s central bank launched a preferential exchange rate for foreign tourists.
Known as the “foreign tourist dollar”, it means payments made on foreign credit cards use the “MEP” (“Electronic Payment Market”) dollar exchange rate, which is currently AR$331.79 to the dollar. In other words, if you’re paying by card, your dollars go 78% further than before. (Source)

Someone on Germany’s Hotukdeals, Mydealz, found a way to exploit it. First, by purchasing 100€ Amazon gift cards via MTCGame.com and paying in Pesos via Visa for 60€. Off 40 percent. He posted his findings on Mydealz.
Others chipped in and found that you can make use of this Peso discount whenever a web shop allows for Paypal payments (so pretty much everywhere): add Visa card to PayPal, changed currency to Peso, use this visa card via PP on checkout.
End of the story: people are buying EVERYTHING with Pesos right now. iPhones that usually cost 900 Euros for 600€, for instance.
The Mydealz thread stands at 81 pages full of comments, as of now. Within two days.
No words from Visa, PayPal etc. as of now. MTCgame has started blocking PP payments.
