I don't have a ton to say, except that this co-op greatly exceeded my expectations. I had been expecting high prices, but what I found was reasonable, and comparable to grocery stores I've been to. The fresh-prepared foods looked amazing, and the cream cheese and vegetables I got were fantastic.
Also, I love buying local stuff, and there is a ton of that here. Became an owner on my first trip.
EDIT: Also, I REALLY want to stress how not pretentious / not intimidating this place was. I've been to co-ops where people sneer at you for having bags with a grocery store logo, and there was none of this here.
