361 days to the sales

I've never understood the January sales, (which used to start in January but got earlier and earlier until they now begin immediately after Christmas - or even Christmas day on the internet). Why anybody would be eager to be up and waiting outside a shop at 9am on Boxing day morning just to save a few bob is completely beyond me.  Haven't they spent enough before Christmas?   And what is it with sofas?  Every other ad on TV seems to be for a furniture shop or warehouse (and DFS, of course). Then there are the Christmas 2008 shoppers. People buying up gift packs from this Christmas which haven't sold and are now on offer at half price or less. Is there anything sadder than hearing someone utter the words - "Oh yes, I do all my Christmas shopping in January" ?
