I'm a Norwegian traveling to the states in November, and I'm planning on buying the iPhone 5S there since it's much cheaper than in Norway. But because I'm traveling to Seattle, WA I know I'll also have to pay tax on top of the base price, and I'd like to keep my spending to a minimum. Here in Europe, if you buy something abroad and travel back to your home country, you get the tax deducted if you show the receipt, so I was wondering if this goes for the state of Washington/US too? And if so, how do I go about doing it?
