Hi,
because the German customs aren`t so strict than the US customs. There is no warranty that you get the cuttings in the US that`s why I prefer buying. But if someone is really interested in trade I will send some.
If I buy some only the German customs check the mail and this is no problem. After the 9/11 the US customs check every mail and they are very strict.
If you can offer some KB please let me know.
