US Black Friday sales up 6.6pc

US Black Friday sales were 6.6 per cent up on a year ago, according to retail data and consulting firm ShopperTrak. The gains were the strongest since 2007 and topped last year’s weak 0.3 per cent rise. The firm, which instals monitoring devices in stores to gauge foot traffic, said many retailers extended trading hours by opening on the night of Thanksgiving rather than very early on Friday. There was an even bigger increase in internet sales, according to research firm comScore, which said e-commerce was up 26 per cent from $648m last year to $816m on Friday.
