It's old but none the less quite informative and relevant to the site. So I present to you BBC's economic take on what will happen next year.http://news.bbc.co.uk/1/hi/business/8429583.stm
To sum it up, plenty of big bargains this year as consumption decreased and stores were left holding excess stock which they then discounted. Less stock will be bought next year, so less likely that big bargains will be had.
That and the 2.5% increase in VAT from Jan 1st 2010.
GDP also increased during Christmas but December also saw Britain set a new borrowing record of over £20 Billion for this month alone. That and conumption on this level won't continue throughout next year, obviously.
