I went to M&S London Colney today (and told it was nationwide) and all their sale clothes had been marked down. This included children, men, women, pjs, bras, accessories, shoes - oh hell - all their clothing ranges... The prices were marked down today!
I found the elmo t-shirt reduced to a pound (pic opposite - on website £4) and a fab dress reduced from £69 to £5. Loads of other bargains going.
