I was in ASDA Gateshead last night (03rd Sept) and they had a 50% off all jewelry and watches upstairs.
Don't know if this is store wide or just Gateshead.
Just a heads up if anyone wants to check there local ASDA - Basically everything they sell in the Jewelry Dept. is 50% the label price.
No Idea when it started or ends.
Looks to be the range on http://direct.asda.com/Jewellery/906,default,sc.html?cm_re=Image-_-Jewellery-_-position1
but they are still full price
