Must be a mistake. Cheaper in Euros or Pounds (outside of Europe).
Wait for a sale directly from Accusonus. I got an upgrade offer from ReGroover Essential to Regroover Pro and all expansions for 60$. Received this offer a couple of times.
Superior Drummer 3 is simply incredible. Orchestral Percussion is expensive, but I understand there's a ton of stuff. Will check this out and may grab it later down the road.
