I want to buy a [digital graphics pad/touchscreen][1] on eBay for technical drawings. 

Because the article's seller is based in Germany, and I live in Switzerland, and because the article is worth more than CHF 200, it will need to be declared on customs, and duty paid. 

Which means I have to pay 8% VAT (for Switzerland). <br />
On the bright side, that means I should get 19% VAT back (from Germany). <br />
However, the eBay sell-price includes VAT. 

How do I have to procede with buying so that I can successfully reclaim the 19% in the end ?
