First months people "fear" of a dollar at 3000 pesos, so the rise prices according to that projection, of course it was wrong. No sells and the latest months they had to lower the prices.
The inflation numbers are a joke, for example, 1kg of yerba mate maybe it cost 1600 pesos, but... the supermarkets offers promotions like "The second one at 50% discount" or "Buy 3 and pay only 2", the price taken for inflation was 1600, not the real one xD, you need to talk with friends from Argentine to really understand the reality, the media is just too ignorant.
