As we are outside the EU, ask the UK online sales office to send the parts without the 20% UK VAT (Sales tax = MWSt or GSA).

You pay the Swiss tax and fees to the postman when the parts arrive.

As you are in a hotel, you might want to use the "Post Restante or Postlagernd" free service here. Example,

Herr

Erich Müller
Postlagernd
8002 Zürich 22
Switzerland

Take your passport when collecting the parcel.
