Questions about Value HDMI (Typ A) — DisplayPort

ACHTUNG: mini-Displayport Connector, nicht Displayport

The price of the 2 metre cable is significantly higher than for other lengths. Is this intentional or a mistake? (Full disclosure: I want to buy a 2m cable ^^) 1m: 14.00 2m: 28.40 3m: 17.00 4.5m: 19.50
