Very pretty white with silver sequins duvet cover sets reduced IN STORE (can't see online) at Asda, maybe store specific- George Home, easy care cotton mix double duvet cover with two pillow cases reduced from £30 to £8!
SEL states £8 & also scans at £8. Not tried Asda bedding before, but at this price would be rude not to :D
Have photo but unsure how to post, will endeavour to tomorrow.
Also had single for £7. Hope this helps someone :)
