WP34S USB and IR board release

[Harald]

OK, we have enough orders for me to make new PCBs.

But another problem has arrisen. I just checked into how I can ship stuff. I used to send these in a standard letter. I think that cost 1,45€ last time I sent anything. However as of 01/01/2019 Deutsche Post does not allow goods in letters anymore. It seems a bad idea to try shipping the kits regardless, as apparently Deutsche Post does pick up on that farily frequently.
The only alternatives Deutsche Post has come up with are
a) "merchandise shipment", which is only available to businesses, and
b) "small package international" wich is untracked, uninsured and 8,89€

Does anyone know what the limit for import duties is in the US (in Germany anything below 22€ is free)? I am wondering if it would be best if I send the kits to someone in the US who could then forward them to people at a more reasonable price then the 8,89€ I can do.
Is anyone happy to help out?

Cheers,
Harald
