Why does the 5-pack cost more than a 3-pack + 2x 1-pack?
5er: 888.-
vs.
3s: 510.-
1-series: 181.-
1s: 181.-
--------------
872.-
In addition, the 1-pack comes with a PoE injector, whereas the 5-pack does not, so in effect you get more for less money by ordering them individually.
Where is the logic?
