Got the same message. I'm guessing that "Amazon listing error" meant someone screwed up and listed what they were charging for a single stick (I've seen other vendors charge 5 or so) plus free shipping, as 12 sticks, and they value the cost of another 11 sticks plus shipping and handling less than they don't want bad feedback. As long as I end up with 12 sticks of Arko at some point (not as though I'm going to use them all at once) I'm happy.
