Brings back memories of 2 months in Argentina and Chile (although this was back in 2008 when the currency was slightly less fucked).
Asking the hostel "Where is the best place to change some US Dollars?" often got some very favourable rates from people at the hostel or friends thereof.
Slight tangent, but semi related and as I recently came across this old pic...
The start of our Patagonia leg. I could barely close my money belt.
I remember the relief when we hit the break even point of our savings from buying Blue Dollars, so being robbed was less of a concern.
