This scam has been around almost as long as ball pythons have.
I've also seen it for exotic birds, spiders, lizards, dogs, rabbits and guinea pigs.
Any time you think to yourself, "Wow! That seems like a really low price for that {insert animal here} you can bet it's a scam.
And if the fact that you didn't ask anyone for the information in the first place isn't enough to convince you, the fact that they aren't in the same country as you are should!
