Hey Katie,,
I ship thousands of dragons a year,, and i use UPs and Airborne express,,,,
I agree with Mickey,, Make the package small as possible,,, and it has to be foam lined,,, and heat packs are a must,,( i see you are Way up north) I would then go down to the local UPS customer counter and have the package sent that way,,, ( UPS does not usually ask what is in the box) and they do ship Lizards as i have a reptile shippers account with them,,, If you use airborne,, they are probably gonna ask "what is in the box?" and i label all my boxes through them as "parts" and i have never had a problem,,,
I mean what do they expect i am shipping with pre printed labels that say"Sunset Dragon Ranch" on them..? My best advice would eb to use UPS for a one time,,as there tracking system seems to work better ,,, and they are easy to ship through,,, and don't want to know what is in the box,,,,, when you ship make sure they do check the box for overnight delivery and for Airborne they check the "noon" box,,, as if it is not checked it will be by 5:00 pm.... hope this helps,,, and if there is anything i can do to help ,, drop me a line,,,
