You can usually find excellent deals at shows. Especially as it starts to wind down. Many keepers would rather sell their critters at lower prices than haul them back home again.

Plus, you get the very important benefit of being able to see the animals in person...handle them if that is appropriate...and talk to the vendors/breeders to get a better feel for their integrity, as well as ask direct questions about the history/care of the animal in question.
