Cheapest way to buy 3 sets of Christmas bedding?

[cherrypez]

I'm twitching over Christmas duvet sets for my 3DDs but wondered if anyone knows where I can get them cheaply, or on a 3 for 2 perhaps? I've spent too much already to justify anything but a total bargain!

Matalan had 30% off Christmas bedding yesterday not sure if it's still on today

Sadly that's no longer on, and I couldn't see any kids' duvet sets on their site. Thanks, though.

Amazon do some for £10 each if that's any cheaper?
