Went into Matalan yesterday and they were putting half price stickers on everything in the Christmas section. This included kids toys, decorations, lights, Christmas cookie jars etc. Also all the gift sets: 'smellies', flavoured oil, pizza etc.
Ideal for the people you don't really want to buy for.
Can only see a few of the items online, so mostly instore.
Some women's clothes - glittery evening stuff - are also half price (though I think there's already been a thread on this).
