Hrrrrrrrrrm...
There aren't really any big stores over here that sell snakes. Pets at Homes larger stores I think have only just started getting corn snakes in but I haven't been in since they did. We've got specific reptile stores only really, and they are few and far between. At least the store I go to know their husbandry for ALL their individual reptiles, and don't only care about the sale. Its about knowledge, and awareness and spreading the love for reptiles. Not sure if I ever came over I'd be able to walk into Petco after what Ive heard/seen on the forums.
