I think its a store to store basis. I know that the Petsmart up the street from me doesn't carry snakes because the previous manager was terrified of them and would not allow the store to sell them. Now that they have a new manager, this one is allowing the store to sell snakes and they should be getting corn snakes in very soon. So who knows what other Petsmarts are doing.

I for one don't really like the big chain stores. I used a local petshop for many years before they closed down. That is where I first started getting into reptiles.
