Why are ball python morphs so expensive?

[Freakie_frog]

I see what your saying, but its not a matter of what they look like its a matter of how many there are. Ya spiders still look exactly the same, but everyones brother, sister, aunt and uncle is breeding and selling them, they are not going to be able to stay expensive. You cant take the supply and demand thing out because thats what it is, pretty much in purest form.

So if the supply is low the price is high ? right
Supply is high but demand is low then the price low? right

So what happens when supply is high and demand is high??
