I just got done reading the tread about Rich Z. "mail order" service. Nothing but great comments about the snakes and the way they were packaged. I am getting a butter from him and he answer all my e-mail in a timely manner. I'm am also sure that the other breeder you will find on the forum have a good rep too.
On the flip side , I have read posts stated that FedEx, UPS or whoevery, sometimes are late ( by hours ) or drop off frozen food on front door step in the heat.
But everything that the breeder did was fine. Most of there business is done through shipping. So each breeder prefers one over the other.
do a search and you'll find for info.
Good luck :cheers:
