Very pretty duvet cover sets reduced INSTORE (can't see online) at Asda, maybe store specific- White with silver sequins, king size duvet cover with two pillow cases reduced from £35 to £9!! These are George Home brand & are 'easy care' cotton mix.
SEL states £9 & also scans at £9. 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. Found at Asda Owlcotes in Pudsey.
