Here in Switzerland, if you buy something from Amazon UK or Amazon DE that is fulfilled by Amazon itself, when you get to the checkout it recalcs the vat (savings for me, Swiss VAT is 7.7%
) and as long as the value is under the Swiss personal import limit (100CHF?) and there is a CN22 on the side, you're good to go, Amazon have sorted out the tax hassles and it comes straight to your door. Over 100 and customs want a handling fee and duty at eye watering Swiss arbitrary rates.
The problem is the 90% of goods I want on Amazon or anywhere else on the internet are NOT fulfilled by big Amazon-like companies and thus you get "This item is not available for shipping to Switzerland". It's been like this for a few years now. All the cheapo Chinese stuff gets straight through, so I get to shop at Amazon if I'm lucky, or Digikey or RS or AliExpress, and that's it.
The only other option is to get things delivered to Germany to a holding address and go pick it up manually and get your customs refund at the border, but that's a bit fiddly. There are many firms by the border that will provide you this service!
At least Switzerland is in Schengen and has free movement with the EU, so we rarely have to show passports to cross borders. But I honestly don't really want to be relying on my UK passport anymore to get around Europe. Sad but true.
Maybe the Calais wine merchants will pivot to become shipping holding companies for frustrated Brits, or perhaps the Scots, if they breakaway
