I went to Lider express in San Telmo. This is what I paid
Coca 1,5 liter 4,39
yogurt serenisma(0,20 cl) 2,49
Nivea soap 1,35
Deo Axe 7,96
Small marmenade 6,29
Speed(Local Red Bull) Can 3,29
Small bag of lays papas 3,95
Oranges per kilo 10,50
That would give you some idea of the prices. If you are from the US and earn in Dollars it would probally even out, if you earn in Euro's and are from Northern Europe it's probally a bit cheaper and if you are here and earn pesos you are screwed
