Blue Haze available now... as used?!?!?! Without selling a copy?!?*!

I wrote a short story for a competition - it went a little off the parameters, but it's better for it!
After its rejection, I decided to publish it - only 6k words (34 pages), so it'll be available on Kindle too in a day or two...BUT...
...it's been available on Amazon for less than a day as a paperback and already it has a price for 'Used'... no one has bought it yet! How can it have a 'Used' price?!?!?!*/*!%!

It's over here on Amazon (the paperback - later the Kindle will appear)
