In a fancy Minneapolis area local small grocery chain, $5.99 per pound (save $2) for "jumbo dark red cherries" (no origin specified in the ad) last week and this week (prices change tomorrow, on Thursday morning) but I looked and passed as they didn't seem like the dark cherries I love. For dark and/or sour cherries, it's a very limited window for local availability, with some from Door Country, Wisconsin, and others from Michigan in general AFAIK. I remember the season as being roughly July and not now.

I've also had wonderful local cherries in season from open air city fruit markets in Germany and to some extent France, and priced a lot less than US$12-17 per kilo..
