Groceries and food (in general) was surprisingly more expensive in New Hampshire and Vermont than Calgary where I live (which is not a low COL area in Canada). I cannot understand how American fruit costs more in the US than they did back home (when including the exchange rate). I was not visiting a premium grocery store (it was a Price Chopper near a Tesla Charger near a small town in NH.)
This generally surprised me because the Canadian "online left" is organizing protests about the cost of food, while I don't see anything similar in the US.
