If you want to sell a creatu at a fixed price then a user is better suited to selling their pets within a rancher or within a forum advertisement. At the end of the day it was a user who chose to start the bid at 1000tu and also chose the minimum bid increment so the low value you are seeing is purely down to the sellers choice. As for on the site as a whole, I think it is important users can set their own prices without a fixed price for a pet in order to meet supply and demand. Economies are never stable and mutant ebilias for example will always be rarer and more valuble in may than they would be just after Halloween ends.
