It's really annoying, it has been popping on and off (fluctuating from $79 to $110) for the last week, and every time I tried to get it for $78, someone else has gotten it since they only ever put 1-5 on at once.
Flywheels is also up, but price fluctuates from $31 to $50 as Amazon US stock restocks and then runs out.
