I am looking to buy something online from Germany which costs €1100. The seller has confirmed that I won't be charged German VAT which is good, however they or their courier cannot estimate what the final price will be (roughly speaking). From experience it all seems to be pretty nebulous in terms of admin charges, and which are coming from DHL/GLS/Fedex/TNT etc.. as opposed to Swiss customs, and why some packages have them and others do not?
Is there a ceiling I should expect over and above the Swiss VAT? Because if its something like CHF 100 in additional charges I might just forget about it
