My sense is that the sale discount is based on an inflated initial price, the seller supplies a brand that is available on Amazon at the reduced rates without discount, the brand the supply is called Cuddledown, their cotton sheets get poor reviews on Amazon and they are available at a lot cheaper than the my duvet and Pillow Website sells them for. Buyer Beware, I can't comment on the quality of the Duvets, they may be good value for money but I suggest shopping around.
I also had same issue last night, and emailed them and ‘.. they were aware of issue with code not working, ..should now be resolved’. I just tried as a test and indeed does!
Code doesn't work.
Not working for me :(
