I thiiiiiink. Alot of the reptiles sold there such as corn snakes and royal pythons etc don't need a license to bring them back. Probably wrong here but i think someone told me once all you needed was a reciept on what species they are, how much you paid among some other info?
Some reptiles, ie the dangerous ones you'll need the license of owning them before buying them, but ones not on the license, you can just bring with the reciept, just bring them in container boxes like the lil food things or if they're bigger in really userful boxes.
well thats what i'm guessing people bring them back in.
