Nisa-Today's converted a record 111 stores to its Nisa symbol group fascia in the year to March, enabling it to reach a 400-store milestone.
The figure includes all shops under the Nisa Local, Nisa Express, Nisa Metro and Nisa Extra fascias.
One of the most significant Nisa Local conversions in the past year was the 2,500 sq ft Nisa Local in Borth, Wales, which was given an innovative look.
Meanwhile, the first M to Go store, supplied by Nisa-Today's, has opened at Moorfields underground station in Liverpool.
Based on the Dutch Albert Heijn model, it will be the first of many to be rolled out.
