If you're going to sell a snake at a lowball price, you better do it with someone you know locally as a local deal or a completely private sale, because you will make a lot of big breeders angry. You can do it, but don't advertise it. As mentioned, these breeders paid a lot and have worked really hard and are not only trying to enjoy the hobby, but are trying to either break even or make a living off of doing this so that they can provide for their family with this as their full time job.
I think you would be pretty upset if you worked at a store and then another store opened up across the street that sold the same merch for 1/2 of the price and no one went to your store anymore and it had to shut down and you lose your job because they can't afford to keep it open anymore. See what I'm trying to say?
So like I said, if you want to sell cheap for fast sale go ahead, but do it in private with people you trust and let them know that you would appreciate this not being advertised either. IF they posted on fauna BOI saying oh get your cheap quality snakes here, this would still have a negative effect.
But again.. I guess this is just MY opinion.
