I'm On a Posting High, Just Roll With Me

This is a 10-Euro bottle of saline solution for my contact lenses that I bought at the neighborhood pharmacy (the only place to get contact supplies). With the current Euro-USD exchange rate, that comes out to a price tag of $12.73. Now, I don't know about you, but I can find no discernable difference between this bottle and the identical one I got in the States for $3.99. Apparently, the inclusion of Spanish, French and Italian text on the label jacks the price up by nine bucks. Do the Greeks know how much this stuff costs everywhere else in the world?
