Where to buy waterproof duvet cover - non-crinkly crisp packet effect

[jsgirl]

We're shortly going to try DS1 without his night-time nappies after a visit to the Eneurisis (sp?) Clinic. The doctor gave us some information which included the ERIC website. I've looked in their shop and the duvet protector is nearly £30. Does anyone have this? Is it extra crinkly? Can anyone recommend a better one please?

Thanks

I use a fabric type shower curtain as a matress protector. You could safety pin one to the corners of the duvet, and slip the whole thing in the duvet cover. I think they all rustle a bit!
