I live in denmark too(bornholm) and as you probably know, there will be random fees including the shipping. If you want anything shipped in, buy from uk. I recommend amazon, me and my friend jacob sometimes buy things there, and while it is costly to ship, it is not as bad as from usa.
If you think about it, it would need to be shipped by ferry or plane, and that itself is very costly.
Get things from uk and germany and closeby countries instead of from other continents. If you need a pricelist from denmark, pricerunner.dk and edbpriser.dk works wonderfully, but they dont always have all products.
If you are looking for a prebuilt custom pc, proshop.dk has a pc configurator, and komplett.dk has komplett pcs. On komplett, value degrades quickly, so i would recommend spending 6000/7000dkk max there.
