"Interestingly, it wasn't the song itself that contained the value; the band released a free digital copy on its website. But the version pressed onto 7" vinyl became a desirable object, the desirability compounded because only 1,000 were released. Limited edition collectables aren't new, but this freemium to physical model is interesting. Is about exploiting that obsessive muso band loyalty and the status that comes with getting a rare and in this case lo-fi collectable."
So the serious money was not online, that's not scarce, it was in the real world.
"The band released 1,000 7" vinyl copies of Fools Day on Saturday, which was not coincidentally Record Store Day."
