I am not sure I understood how it works.. and cannot find the right thread here (which I am sure there is.. so if someone wants just to point me to that..

Anyway, I have always ordered books from Amazon and I even got them cheaper (without VAT).
Last time I bought some games for my partner too and got to pay the postman around 25 francs (which was absolutely fine as it still worked out cheaper than buying them here!). But I did not understood if the fee was for the games or for the total amount?
I am now thinking to order some stuff for my cat from zooplus (the german site).. will I have to pay a surcharge once the parcel gets delivered (and how can i calculate how much will be)?
thanks for your help..
