Mothercare 50% off selected duvet sets + BOGOF
Lots to choose from.
Anything with the 'special offer' banner under it shows as BOGOF before you put your card details in.
There are some lovely sets - some examples in the first post.
(The BOGOF only showed once I've gone past the payment page where I put in my credit card details. It showed just before confirming and placing the order, last step of the order process)
