There are some people that breed snakes for a living, and there are others that breed them simply for hobby.

I myself am a hobby breeder, meaning that I do not make my living selling the offspring that I produce.

To establish my collection, I aquired the best looking examples that I could find, of the base morphs that I desire to keep and work with.
Each one has the look that I like best in that particular base morph, and the look that I wanted passed on to the combos that I produce.
I selectively breed my animals based on what I would like to add to my collection, and which of my animals I think would make the best examples of those mutations.
I hold back the majority of my hatchlings, and would actually prefer to trade the others then sell them. However, sometimes I need to sell an animal for cash, in order to redistribute the funds back into my hobby. That may mean building and stocking another rodent rack, picking up another Helix DBS-1000, or simply moving out animals that I already have in my collection, in order to purchase mutations that I would like to add to my collection.

There are at least two types of "professional" snake breeders.
( You know, the ones that intend to make their living selling the offspring that they produce. )

The first type of "professional" breeder, selectively puts together their collection of snakes, by purchasing only high quality breed stock animals that have the look that they like best in that particular base morph, and the look that they want passed on to the combos that they intend to produce. These people produce high quality animals, and their prices usually reflect the high quality of their animals.
This type of breeder is often, but not exclusively, made up of hobby keepers / breeders that have decided to turn their hobby into their career.
Due to the higher quality, and therefore higher priced animals they produce, their customer base consist mainly of two types of customers.
1.) Hobby keepers / breeders that would like to turn their hobby into a career in the future, and become "professional" breeders, and are willing to purchase high quality breed stock animals.
2.) The wealthier and/or more selective hobby keepers, that can afford to, and are willing to puchase higher grade animals at higher prices for their personal collection, even though those animals are not an "investment."

The second type of "professional" breeder, puts their collection together by purchasing wholesale lots of animals, often sight unseen.
Their operation is simply a numbers game.
They mass produce animals and their customer base consist of other type 2 "professional" breeders, show vendors, and the hobby keepers that would like to have a collection of assorted BP mutations, and would rather purchase, or can only afford to purchase the more affordable, B grade animals.

Unfortunately, there are way more animals being produced, then there are people looking to purchase those animals.
The supply is definitely greater then the demand, and both types of breeders are competing for the same sales.
Most Pastels are not what they used to be, and other mutations are getting less and less impressive as people throw any two animals of the opposite sex together, in an attempt to put as many eggs on the ground, in order to try and recoup their "investment."
