Take a look at this
If you check the time stamps of the posts, that supposed listing was up at 6:42 and taken down in 40 MINUTES later. As an Amazon regular I know that's something called a website glitch which has happened a few times with amazon high-end products. It has to do with bugs in amazon's automated pricing algorithm.
The Beyer ad was not a website glitch because it was up for a day (unless buydig is really slow).
