Here is what I found on the 4 in law... I understand that it is only unlawfull to sell them if you are associated with a business? But that it is not in anyway unlawful to own them. I dont know for sure but this is supposed to be a copy of the law? Read it and see what you think. Four Inch Turtle Law
The sale or commercial distribution of viable turtle eggs and small turtles (carapace length less than 4 inches) for use as pets is banned under 21 CFR 1240.62. The ban is based on the Public Health Service Act (section 361, 58 Stat. 703) and therefore applies to both intrastate and interstate sale and distribution.
Exceptions to the ban under 21 CFR 1240.62 permit sales of turtles and turtle eggs for use in bona fide scientific, educational, or exhibition purposes other than as pets and of marine (ocean) turtles. Other exceptions to the ban are the sale of turtles and turtle eggs not in connection with a business (e.g., limited sales between turtle fanciers have been permitted) or that are intended for export.
The ban applies to small turtles (under 4 inch carapace length) because these are most likely to be held for sale as children's pets, and the purpose of the ban is to protect children from turtle-born salmonellosis.

I agree about the shipping, just overnight them to your destination and they should be fine. This is how most turtles travel anyway, even the ones in pet stores, they have to come from somewhere.
