Lego releases an employee exclusive

Every year Lego gifts employees with an exclusive Lego set. This year, the employees were given Lego Klando Campus to celebrate it's 15th anniversary, it's set number 4000018.
This isn't the first time Lego has released a set of Klando Campus, they also released a set back in 2012, with a set number of 4000006.
Of course it isn't surprising, if you compare the packaging of the boxes, the campus has clearly grown since then.
Images of the 2015 employee gift set have surfaced on second hand markets, such as Ebay and Bricklink, with a starting price of $150 up to $400.
It's also interesting to note that most of these sellers seem to be from Czech Republic, so they may have gotten theirs earlier.
