Found it lurking in my spam folder purely by chance yesterday evening - apparently there is a preview sale running from yesterday to tomorrow - managed to get a slot this morning and got some bargains on childrenswear, childrens toys and hovered over the half price 7 jeans for ages but managed to resist.
I do normally get the preview email but have never known them do this pre Xmas before - link attached, not sure if it will work but should give listing info..
