Try to avoid buying from tables that have all sorts of different reptiles on their table, many times they are jobbers, they never bred the animals, they just acquired them and are flipping them. Many times, they don't practice good quarantine, and it's difficult to reach them after the sale. They probably acquired them in a trade from a show the weekend before.
I have been in the market for an albino male, and I've found one from a member here. He quoted me a price, but encouraged me to attend the show the next day to make sure I didn't find one there that I liked more.
I did find one of similar looks, on a jobber's table for $100 less (minus shipping as well). I left the show without the snake, and called the member here to tell him that it was a no brainer for me - I'd rather pay $100 more for HIS animal. I know that the animal is being well cared for (we may wait on delivery for another show so that we can meet each other in person - about mid-way between us), and that he's being treated as well, if not better than his own animals.
The service that I've already received far exceeds my expectations from a breeder. I'll happily pay a good breeder and fellow BP.netter more for the VALUE of being there for me before and after the sale. I love the updates I get (without asking) on my boy.
