Amazon reports record sales of $21bn The world's largest online retailer on Tuesday night reported record sales in the final quarter of 2012, as more consumers did their shopping on the internet. International sales, which includes the UK, jumped 20pc to a record $9.09bn (£5.8bn). That helped drive Amazon's total sales in the quarter to $21.3bn, up 23pc from 2011. "The market is underestimating the long-term international sales opportunity," said Scott Devitt, an analyst at Morgan Stanley. January has already proved to be one of the most brutal months on record for British retailers, with HMV, DVD rental chain Blockbuster and camera group Jessops all collapsing into administration. "The failure of high street players will just drive more people to Amazon," said Neil Saunders at retail analysis firm Conlumino. Now that Jessops has gone, if you want a camera, you're more likely to go to Amazon. Amazon shares surged in after-hours trading in New York after the retailer's operating profits of $405m comfortably beat a forecast the company gave Wall Street in October. The shares climbed 8pc to $282, as investors were cheered that the Seattle-based company is making money despite the billions of pounds it is investing in new warehouses. Mr Saunders said Amazon will continue to grow its share of consumer spending in the UK this year, heaping pressure on traditional retailers. Amazon, which was founded by Jeff Bezos in 1994 as a bookseller, said that sales of electronic books surged 70pc, while sales of physical books saw their weakest growth in the company's history. "We're now seeing the transistion we've been expecting," Mr Bezos said of the shift in book sales. Morgan Stanley estimates that by 2016 Amazon will have almost a quarter of an global online shopping market that will be worth $1 trillion. David Cameron said last week that the public had had enough of companies that sell in the UK but use " complex tax arrangements abroad to squeeze their tax bill."
