I like it, it's coming along very well. IMHO, I wouldn't ship geckos in weather above 90 degrees. Even if you're going to add a cold pack, it's just too risky...you have to add an extra 10 degrees for all the time those animals have to sit on the truck. So if it were me, i'd state that I will not ship in weather below 50 degrees, or above 90 degrees.
Also, your "How To Pay" section should go along with your "Payments" section at the beginning.
It has a lot of potential, and I really like how the picture of your gecko comes up while your waiting for the page to load!
