beware of amazon.com prices

I live in Sweden. Don't know if that matters. Maybe there is a fee for currency conversion or import or something. The price that I checked was the price converted to Swedish crowns, but that should not matter. Anyway, the actual price charged was as I said between twice and four times the price that amazon told me that they charged me, amazing. I use amazon.com and amazon.co.uk depending on which is most appropriate at the moment.
