Though it may be possible to ship small parcels with DHL for lower shipping fees from Germany to most countries in the world, please take notice of my shipping principles here, caused by bad experiences in the past:
Attention:  I basically do not ship without registration, insurance and tracking services!
Combined shipping: I support combined shipping as far as it makes sense and is possible.
