Even the monkey in one of the seller's photos is embarrassed by the prices.
Still, you get what you pay for.
But if I paid 600 CHF for a second-hand duvet, I'd expect to get a sleeping partner to go with it included. Second-hand, of course.
Btw, if you really
do want quality furniture, drive an hour from Zurich, and pop over the border to Dick. Same quality as Pfister, cheaper prices, and then they'll knock off the 19% German tax, then add on Swiss tax, and delivery to Switzerland.

The quality of Dick is unbeatable (fill in your own double entendres here..)
On the way to Dick, you'll also pass Möbel Arena. Kinda like a slightly-better-than-IKEA alternative. We got our kid's bed from there, and again, they take off the German tax, add on Swiss tax, and charge about 60 CHF for delivery to Switzerland. Very good service...
