Promotional activity in the run up to Black Friday attributed to tumbling prices.
Data from the British Retail Consortium and Nielsen has shown that prices in UK shops declined by 2.1% in November.
The fall – which matched the record drop reported in March and beat the 1.8% decline from October – was mostly attributed to heavy promotional activity in the run up to Black Friday (November 27).
November was the 31st consecutive month that the BRC’s Shop Price Index has reported falling prices.
It was non food retailers that suffered the most, reporting a 3.3% drop year on year. This was driven down by promotional activity on clothing, footwear, gardening products and electricals.
Meanwhile, food prices fell by 0.3%.
Helen Dickinson, chief executive at the BRC, said: “Although the survey period does not cover Black Friday, it is likely that some retailers were discounting early in November in order to spread consumer spending over a longer period.
“Electricals for instance saw prices down 4.3% on last year.”
