Be careful about who/what you buy. I'm as small time as they get in terms of breeders here, but even so I've sent snakes all over the country to people I've never met before. I even conducted some transactions, usually hundreds of dollars worth of business, without ever speaking to the buyer in person. I've always wondered..."wow, this guy just paypaled me 750 bucks and doesn't know me from adam". How do they know that they can trust me?
Well, here's what I can offer them...references. Yes, I know references can be fudged, but thats one good way to ensure that the people you buy from are on the up and up. I've maintained an e-mail list of all the people who have bought from me in the past (I work very hard to make a "customer" happy. I represent my animals exactly how they are, I pack them meticulously for shipping, include detailed feeding records, genetic backgound and photographs, etc.). If someone asks, I sent them the list of names and e-mails. I know that occasionally my references have been contacted.
I know you've been burned before, but if you do your homework you can buy from both large, well known folks, and the little guys like me, with confidence.
P.S...having said all that, I've personally only bought on-line from VPI, Ralph, and Ben Seigel. Not that I wouldn't try another little guy, just the "big boys" just happened to have what I wanted at the time.
