Well, as I've said, it could be that customs have our items, if indeed he used Premium German Post shipping, because as such it's a target for more detailed inspection and if so, you "COULD" get additional delays. This "superior" type of shipping offers insurance and tracking usually, however it also has a higher probability than regular airmail to get stuck in customs with these annoying delays.
Anyway, lets wait until Friday night and if nothing arrives by then, we should e-mail Tibor for more info.
