I can't find the history of the transaction for when I bought them, so I've completely forgotten what I paid. I did set up what I consider to be a high buyout price to see what is offered!
I would greatly appreciate help in finding a price that is fair - not too high/too low!

Slaneesh - 800+ stats; Jet base, Black mane; five markings with one hidden (should I use the scrying stone to find out what it is?).

Any and all help is appreciated! I have mostly sold.. fodder so far.

Edit: 15-20GB sounds fair imo, but it's really hard to determine was goes into pricing. Especially with the lineage having the Big4/Big8 in there at least once.
