Considering they were on Century Media at the time, which only sells to the fans and not to the masses, I doubt it sold very well at all. Bands like Metallica, Rush, Tool, APC, etc. are on labels that promote EVERYWHERE. It's just more proof that the crowdfunding is the way of the future as far as music is concerned. The money goes straight from the fan to the artist, with no label middleman. Sure, big bands like Rush and Metallica would lose the worldwide promotion, but for bands that are on labels like Century or hell even Nuclear Blast (who already only promote to the fans anyway), they're hardly losing anything at all.
