Let's say you order a book that costs CHF20 from Amazon.de to be shipped to Zurich.

How much additional would you have to pay normally?

Shipping?

Customs?

Other fees?

Amazon.de ships books free of charge to Switzerland.
Tax/customs is not charged for just a CHF 20.00 book. I don't recall the limit, but it's something like CHF 60 - 80.00.
Check out other threads - this has been discussed in detail before (scroll to bottom of this thread or use search function)

Here's all the info you need in German and (google translated) English.

... so it's free from EUROs 20.00 then, not CHF 20.00 ... I stand corrected.

you might also want to check bookdepository.co.uk since they deliver worldwide free!

Use play.com if you can.

The Germany page also says: 'Buchbestellungen, auch in Kombination mit Artikeln aus den Kategorien Musik, DVD, VHS, Games und Software, liefern wir in diese Länder auch unter 20 EUR Bestellwert *kostenlos*. '

<<Book orders, also in combination withe articles of the categories mucic, DVD, VHS, Games and Software are delivered to these countries even below the value of 20 EUR 'free of charge'.>>

Switzerland is part of 'these countries'.

They change these conditions from time to time to either include or exclude books costing less than 20 EUr. So watch out each time you want to place an order.

Amazon.de does include shipping to Switzerland in the cost of the books. You will pay customs if the total bill is over a set amount (approx. CHF 60?). However, it is worth comparing prices to amazon.co.uk and amazon.com. Occasionally I have found it cheaper to order from these sites even with the extra shipping costs (also extra mailing time).

No no no ! This is what amazon.de says on the subject:

http://www.amazon.de/gp/help/custome...nodeId=1055388

'Nettopreis für Kunden in der Schweiz: EUR 130 - Steuerbetrag 3,12 EUR (unter 5 SFr) -- hier wird keine Steuer erhoben'

<<Net price for customers in Switzerland: EUR 130.-- - taxable amount 3.12 Eur -- here no tax is asked for..>>

'Nettopreis für Kunden in der Schweiz: EUR 150 - Steuerbetrag 3,60 EUR (über 5 SFr) -- hier werden Steuer und die Postvorweisungstaxe von zurzeit 10 SFr erhoben.

<< Net price for customers in Switzerland: EUR 150 - taxable amount 3.60 EUR -- here both tax and the fee of the post office of 10 Fr have to be paid>>. I personally believe the post office fee may have increased meanwhile.

Nothing prevents you from placing several orders with amazon.de to avoid unnecessay fees.

I suppose you all know that amazon.de deducts the German VAT and Switzerland does not charge VAT on books.
