I help out at the Bowling Green reptile lab's table so I am there from start to finish. I have gotten deals at all times of day. Sometimes vendors with a large stock of animals (like ball and corn hatching season) will put more out as some sell so the best one might not be on the table yet. Also some of the smaller vendors leave once they have sold most of their animals so may be gone a couple hours before show end. In addition to that you have the people walking around selling animals they don't want or can't keep and they can be there at any time of day. If you have the money buy what you want at the beginning and then stay to the end to get deals and too make sure you didn't miss anything.
