Total food sales grew 0.1% over the three months to November and 0.3% in the 12 months, but declined on a month-by-month basis. Non-food sales were up 3.5% over three months, ahead of their 12 month average of 2.9%.
Online sales on non-food profits in the UK grew 11.8% in November, compared with a year earlier when they had grown 12%.
