That's what people here in Los Angeles are paying too for commercially produced eggs. But there are those who will voluntarily pay more IF they believe animals are being treated humanely. And that's what I heard was driving the demand up there.
When I lived up there in the 80s I made my monthly drive to Bellingham, WA for things too. I was aware of the demand for US prices on mail, gasoline and dairy products. For me, it was what the kids saw on American TV commercials that they just had to have. At the time, that included Happy Meal toys as Canadian fast food spots skipped those promotions.
I used to buy dozens of Happy Meals, chuck the food and take the toys back to the neighborhood. A happy, if odd, memory!
During my most recent residence 5 or 6 years ago currency was at near parody. I'm sorry it's taken a tumble.
