Q.V.C. have an outlet called Northern nights, who sell gorgeous down duvets at a very reasonable price. I paid less than �90 for a king size duvet, which is so light, when I throw it up, it floats down slowly, yet it is warmer than any average duvet. Northern Nights also sterilise ALL their feathers, and down products, and NEVER use feathers in their duvets, (only100% down) and they are all washable.
I do not buy any bedding from anywhere else but Northern Nights, as the quality is 2nd to none, but still reasonably priced.
Try googling ....... qvcuk.com and look for the Norhtern Nights outlet on their website.
