Unfortunately, it will be very expensive to ship to Germany. It will cost about the same to ship a couple of snakes as to ship 100 snakes. That is because most of the cost is dealing with government red tape, not the actual freight.
The cheapest way to do it is to get together with an American breeder or dealer who attends the Hamm show in Germany. I believe the shows are in March and Sept, but you can Google that. Glades Herp usually goes, and so does Mark Bell from Reptile Industries. I have used both of them to ship animals to my European customers for me. Or find others online who go to it, and who might be closer to you. Since they will already be shipping a lot of animals for themselves, they can take on others more cheaply than when shipping only your few separately. They do have to pay an import tax on each animal, though. It will still probably cost you a couple of hundred dollars or more (vs. $500 - $700 using a broker for just your animals alone). The only other legal way to do it would be to get your own import / export permit ($100 per year), pay your own inspection fee ($55 last time I checked) and drive the shipment to an international port such as Miami, NY, etc, and file your own paperwork. Many airlines will not accept such shipments from unknown shippers, and will force you to use a broker. It is a shame that it is so complicated for animals that are not protected in any way!
If you will be there for a year or less, I would try to find somebody who will babysit them here for you. If you will be there for at least a couple of years or more, it might be worthwhile to make arrangements to pick them up at the Hamm show - that is the cheapest and easiest way I know about. Of course, you will still have to ship them to whichever dealer is going to take them there for you. But that is easy - no government red tape to deal with.
Believe it or not, it is the same hassle to ship even 1 mile across the Canadian border, too! Your tax dollars at work, lol!
