Upside is that at expos you can look over the animal yourself and maybe even have the seller sex it for you but as mentioned just make sure the seller is reputable and you shouldn't have issues. I personally have bought more snakes online than at expos. Check Fauna's Board of Inquiry on a seller you're thinking of buying from (search their name): http://www.faunaclassifieds.com/foru...splay.php?f=13
