Noticed on Discogs that Other Music is selling a second copy for $4,500. If legit, the description reveals some interesting info:
"Other Music was given two copies of this mystery record on Record Store Day in 2013, one to give away and one to keep. Here's the second copy...unplayed in perfect condition."

So does this mean that each of the known stores in fact got 2 copies, thus meaning Rough Trade and Avalanche Records have second copies as well?
