Tesco, Asda and Ocado increased the number of promotions they had on offer in September, according to data from the latest just-food Promo Tracker.

Sainsbury’s was the only UK retailer of the four monitored by the tracker to run fewer promotions in September than a month earlier.

However, the data, compiled in association with mysupermarket-insights.co.uk, showed that the proportion of SKUs on sale at Tesco fell during September. The average saving per promotion at Tesco was also lower.

At Asda, the UK’s second-largest retailer, both the proportion of SKUs on offer and the average saving per promotion increased.

Meanwhile, at Ocado, while the percentage of lines on promotion increased, the saving on offer fell.

The proportion of SKUs on promotion at Sainsbury’s fell as did the average saving of its discounts.
