I'm a mid 40s Canadian in Toronto. That used to do roadtrips to the US in several year intervals since the 90s. Like all things, it used to be way cheaper in the US, even when our Canadian Dollar was a pittance in 2001. Going outlet shopping was a rite and normal in the 90s/2000s.
2000s, cheap everywhere still. Especially when the CAD strengthened. Everything.. supermarket, chips, snacks, fast foot, restaurants.
Went recently (2024 LA, later 2025 Vegas) and man, the price of a bag of chips, $6-$8 dollars even at places like Trader Joes. The equivalent in Canada is like $2-$3 USD. We both have similar options for potatoes.
What happened specific to Potato Chips?
