Ok, so fair question, albeit a poorly worded question.
It's all nonsensical complaining...the ball python market is arbitrary at best. There is nothing to regulate it.
There is no mark up because there is no set market. People charge what they can get, and NERD can command higher prices than most. Does that mean they're being unfair? Not at all. You can buy an "I Love NY" t-shirt in Times Square for $25, and you can buy that same exact shirt at a rest stop in western PA for $8.50...does that mean that the guy in Times Square is being unfair?
Saying that NERD is selling at "mark up" prices is ridiculous...and you will surely see this when you go to sell snakes and see how many people out there are selling animals at $0.40-$0.50 on the dollar of so called "market price", making it more difficult for you to sell your snakes...you'll be much more appreciative of those who price and can actually sell at premium prices.
That may be because there are a lot more hypos out there.
