if I dont live where somebody else lives, I am not "real"?
There is no question that my US social security check means I make more than many Argentines.
but there is a wide range of food available in most of Buenos Aires.
I have never had a problem finding decent verdulerias or carcinerias in small towns in the provincia, either.
There are farmers markets one day a week in dozens of barrios here.
If you go, and talk to the vendors, it is often possible to get deliveries.
we get in season produce, eggs, and fruits dropped off at our house by one vendor, assuming we buy 10,000 pesos or so worth at a time.
Shopping in Argentina is personal, and requires time to build relationships.
It requires investment in trying different vendors local to you, asking questions, and with time, you learn, who has what, what days they get deliveries, who is cheaper, and so on.
