That's because your asking for to much. Mert Keklik is not worth 1.2mil at 29 tears old.
I had him at 1M, no sale.
Had him at 750k, no sale.
So now I have put him up again, but overpriced just for the hell of it. I've sold a couple others with slightly lower skills at the same age for 750k, and for some reason can't sell Keklik.
