Because CafePress only ships from the US, and once shipping and tariffs get factored into the equation, you end up paying nearly twice the price for whatever you order.
I've only bought from them once. I bought merchandise for about 600 dkk, and ended up paying just under 1100 dkk.

Shit...
Thanks for the tip, I was thinking of buying but seeing as they only ship from the us it's unfortunately out of the question :(

Yeah, Told & Skat really squeeze you hard when you order stuff from outside the EU. You can see the rates here. The trick is never to order anything from outside the EU worth more than 80 kr.
Actually, the dollar is exceptionally low at the moment. Hang on...
No, not quite that low. At the current exchange rate, the cheapest "DRM Free Revolution" T-shirt costs $19.99 = 99.39 dkk. Add in VAT and the tariff fee, and you're suddenly looking at 279.24 dkk, or $56.16. That's a hell of a price for a T-shirt :-(
You see that calculation GOG? PLEASE find a store that ships from the EU. Pretty please?

Seconded and willing to buy a few items if this comes true.

any Hoodies with the vertical logo coming? it is winter ^_^

Thought of doing those laptop sticker things? The DRM Revolution would brighten up my otherwise mundane dell mini 9

And now to hint my mom what I want for Christmas...After I convince her that her credit card information is safe and she needs to stop listening to the news.
AWESOME SHIRTS!!!

Thank you. *gives grandma's cookie* :3

That sounds good. I think a lot of your European customers would love to buy your merchandise, but won't because of the insane extra charges levied on us when ordering from outside the EU. I do think Denmark is one of the worst places for doing it, but I'm sure there are pretty steep fees involved in many other countries too.
Just to hammer the point home: Let's say I want to support GOG by buying (and wearing) one of your T-shirts. That will cost me $56.16. And how much of that money will GOG actually receive? Exactly $1. I happen to know this because I have a webshop on CafePress myself (that I only ordered from that one time I mentioned earlier), and so I know that the base price of a dark T-shirt with print on the front is $18.99 there. Meaning that is what CafePress charges for it, and shopkeepers get the difference between that $18.99 and the price they sell it for. So for a payment of $56.16, I only get to support GOG with a single dollar. I do want to support you, but not at that price.
