Not quite, we have a local pet store over here that offers amazing prices on their reptiles. Like most kings and their morphs being only $30-40 and corns ranging from $10-40, iv even seen regular balls go for $20. These arn't because their sick or low quality reptiles, its because the guy breeds sooooo much snakes he makes profit either way.
BUT if your talking about a pet shop that buys reptiles from breeders and flips them at a high price then yes you are very correct lol.
