This year’s shopping sales extravaganza is likely to have a feel of going, going, gone, with many items set to get more expensive. As the clock ticks down to Black Friday, aggressive promotions on everything from 4K TVs to tablet computers and winter coats could be the last hurrah for shoppers before price hikes in 2017.

After bargain-hunting consumers went on the rampage on Black Friday in 2014, fighting in the aisles for cut-price widescreen televisions, last year it was a much tamer affair, as shoppers retreated to the safety of seeking the best bargains online.

This year, there is likely to be more of a sense of going, going, gone on the high street’s hottest deals, because retailers across the board are signalling that the weakness of sterling will push up prices in 2017.

While just over half of businesses participating in Black Friday anticipate higher sales this year, fewer store chains are taking part, according to an industry poll by Barclays.
