Re: Getting VAT back on departure from Switzerland
The shop you buy it from would have to generate the paperwork, though I'm not sure if the places that sell laptops and the like here have tax-free shopping like many of the luxury goods retailers. You'll then have to show the merchandise and have the paperwork stamped on your way out of the country (there's a special place to do this in the airport), put the forms in the mail and the VAT should be refunded to your credit card.
I did this years ago when I visited here (before moving) and purchased a handbag in one of the boutiques, and, frankly, the tax refund wasn't that much since the VAT isn't as high here as it is in France or Germany.
