I may just be the last to know this, but was in there yesterday and tops and bottoms (not dresses or nightwear), were "buy one, get one half price". So, got two pairs of really nice trousers (in short length for my height deficiency) for £45.
They had lots of "tiny baby" stuff left in the sale as well, if anyone knows of people needing to rush out and buy stuff for an early baby.
