You need an insulated box. Shipyourreptiles.com has all the boxes you would need. Pick the size that is appropriate for your cham. If you cham is larger, put him/her inside of a cloth bag, and add balled up newspaper for padding and place the cham (in the bag) on top of the newpaper in the box, then add a couple more pieces over top for more padding, but not so much that when you close the box it restricts movement. You must have your shipping label printed, and the box completely ready to go before the ups store can manifest it. Call them, and ask when the overnight shipments get picked up, and drop the chams off like 30min-1hr beforehand.
