The reason is because the company would not make cash which is really all corporate cares about. Breeders are not going to wholesale their nice stuff. Now as for normals, they might wholesale those assuming they get many if any and also depending what they are het for.
Heck i was on the local reptile FB page and someone posted a poor little GTP at a local Petco, i think in federal Way or Auburn...somewhere down south. They didnt even give the poor guy a stick to sit on. He was curled up on the floor inside a half log hide. Not sure if someone went to rescue it. I felt bad for him and if i had the caging and the cash, i probably would have gone to rescue him. I know its not a good idea as it just reinforces that said animals will sell and they will just order another which will be kept in the same condition but i felt so sorry for that little baby snake. Was like Dottie my pied BP, when i got her, she was in the back room in a little tiny cube that was half filled with cold spilled water in a mess of slop. They had to assist feed her as they said she didnt eat and was very bitey......2 days after i got her home, she ate like a horse every 3 days and has only bit me once in almost 5 years and that was because my finger smelled like a rat as i was messing with them and forgot to wash my hand lol.
