Amazon UK sold approx. 64 items per second during Black Friday 2014

"Black Friday was the busiest day on record for online retailer Amazon UK, with sales that "surpassed all expectations", the company has said.
Its website recorded orders for more than 5.5 million goods, with about 64 items sold per second.
Amazon said the public's appetite for Black Friday was "bigger than ever".
However, the day was not without controversy as police were called to deal with scuffles at a number of retailers' stores across the UK.
And some online retailers reported problems with customers accessing their websites because of sheer demand.
Last year's Black Friday was also a record day for Amazon, when it sold more than 4 million items."
