You may be writing of these already, but at Costco they carry a line of sugary goodies from a local company called Dilettante Chocloates which contain not only choclate covered blueberries, but also strawberries, apricost, and about four other choclate covered fruits.

Don't know if they ship all the way to your locale, but if they do, check them out.

Our first convenient Costco is supposed to open near here soon. We've already got Sam's (WalMart owned) and BJ's (I love BJ's, and I love saying it loudly to my wife's great chagrin), and both sell chocolate covered fruit. I love the blueberries and raspberries, but haven't tried the others yet. A king-sized bag of dried apricots makes me a happy camper.
