Forbes.com: Sweet Profits

Not so long ago, in candy stores not so far away, anyone could snag a bag of Masterfoods' limited edition Star Wars dark chocolate M&M's. But since their release in collectible packages in April, the ten-week window of the promotional product has long since closed, leaving many craving more. And now some speculators have stepped in, tasting some sweet profits.

This article is slightly out of date now, since dark chocolate M&M's were re-released in late September through early November. What is still relevant, though, is they were impossible to find. I snagged 1-1/2 lb. at M&M's World when we were vacationing in Las Vegas, but once they're gone, it'll be tough (impossible?) to go back to boring old milk chocolate.
