I can't find any documentation to support to Klok G`Rshai was a greedy vendor on live, ZAM says nothing of the sort, nor does EQTraders.
So I compared her prices to notorious greedy vendors from the outpost
Klok (indif) sells
A Rare Leaf for 28pp
A Root for 13pp 2g
A Cockatrice Beak for 40pp 7g
Tin Merchants (indif) sells
A Rare Leaf for 28pp
A Root for 13pp 2g
A Cockatrice Beak for 40pp 7g
They both buy at half price, so she's basically on the same vendor model than he is, she's a greedy vendor here.
From what I can find on the internets, she should vendor as a regular vendor, taken from this vendor database:

A Cockatrice Beak 20.212
That's about as accurate as i can be with a 15mins google search, i can't seem to find a list of greedy vendors anywhere (you'd think that someone would have done it in ten years) and zam doesn't list vendor prices other than base goods.
The next best thing would be for someone with an EQMac account to double check there, but I don't, as I don't believe in the Steve Jobs Jesus.
