For everyone feeling the pinch, I would suggest shopping at small shops - you know, veggie place, bakery, chicken place, meats place.
While shopping at supermarkets (Disco, Jumbo) is certainly really quite pricey now, I still find shopping at these small places gives me far better value for money than Canada. In fact I'm amazed at how much I get for my money on a daily basis. It is so much more expensive than before but still, the value is there.
And even then - bag of green grapes at Disco for 11 pesos? In Canada, that could very easily be $9-11. There are still good deals on fresh produce overall. It's the packaged foods that can be shockingly expensive. Nevermind alcohol - there is NO wine, nevermind decent wine, for under 35-40 pesos in Canada. A very average bottle starts at 40 pesos. If you go to a restaurant, a bottle of wine will never be less than the cost of your main entree.
I'm not suggesting that Argentina and Canada are comparable in terms of cost of living/ spending power etc - of course not - but I just think it's kind of silly to act as though Buenos Aires is now more expensive than Canada (and much of Europe) when for many (not all), their grocery costs are more along the lines of shopping at premium grocery stores like Whole Foods or, to a lesser degree, Loblaws.
Going out for dinner? 1-200 pesos to be stuffed and wined at nice enough places (more for nicer, obviously). With apps, a drink and a main, you can spend that (and probably more) at horrible chain restaurants like Olive Garden or East Side Mario's.
Again, not saying prices aren't creeping up majorly, I just don't agree with the view that it's more expensive here in the least.
