I think it comes down to doing your research as a buyer... If someone wants to pay 2-3x the going rate for a morph, then they can.. I wouldn't do so, but I'm aware of the tools we can use to look at pricing in the market (MM, KS, Fauna, etc.). Newcomers might not have that info and just buy from a "big name".

I am fine with breeders pricing a little higher for quality and high standard of care. I recently bought 2 BPs for a future breeding project. One came from a small breeder who had excellent communication, sent pics, hatch date, attempted f/t feedings for me, etc. Great snake, great feeder, and great sales experience. I'd purchase from that breeder again even though their pricing was higher than others on the morph I purchased (which I didn't realize until after the sale).

Second purchase was from a much larger well-known breeder with a good rep. Animal should have been a much higher-cost animal that the other purchase (1st purchase was a recessive animal with 1 additional codom gene, 2nd purchase was a recessive animal with 4 additional codom genes). I paid around $50 more for the second animal (including shipping costs). However, communication wasn't as good, animal was healthy, but smaller and is a much more finicky eater.

Both purchases ended with healthy animals, but price and service were a lot different and in this case, the big breeder was selling his animals for a lot less. Note that this big breeder doesn't have a youtube presence that I'm aware of.
