Well, I'm in Paris right now, and was just in Madrid. In these two European capitals, supermarket prices (for an equivalent product of equivalent size) are either on par or (usually) less than in BA. 500 grams of Italian pasta in Paris is actually cheaper than 500 grams of Lucchetti in Disco. Bread, cheese, produce, chocolate, jam, coffee, wine, canned goods, toiletries -- all cheaper. Even the freaking Havanna alfajores and San Ignacio dulce de leche imported from Argentina cost less in Madrid than in BA. I'm paying less for my furnished, short-term rentals here as well. So other than the bus and subway, WHAT exactly is driving these rankings?
