While I also think NERD's prices are on the high side, he can charge what he wants, and obviously he's selling enough animals to stay in business.
Do I think his morphs are better than anyone else’s and deserve the higher price points? Depends on the morph. Personally, I wouldn't put either Queen Bees or Super Flys in that category. Especially Queen Bees, as there are lots of breeders out there producing great Bees at significantly lower prices.
On the other hand, If I were in the market for a Soul Sucker, there's only one place I would go, and yes, I'd pay the premium.
Please keep in mind that being the biggest breeder on the block doesn't automatically make you the best breeder on the block. At this point in the history of the BP trade, there are many small hobby breeders out there consistently producing high quality animals. The trick is to find out who they are and develop a relationship with them.
