I think the prices on everything sounds pretty decent, except for the Woma male. He's way over priced .
Womas are a bit more uncommon and don't have the wobble issue ,but are still almost right next to spiders in price.
There's a breeder sized female woma over on fauna for less than him males listed for $100, some already proven breeder. This guy asking 500 for a male woma that isn't even a breeder is a bit ridiclous.
