Grocer 33 mystery shops to pit stores against local competition as part of overhaul

Published on The Grocer

The Grocer is upping the ante with major enhancements to its flagship Grocer 33 mystery shopping competition for the start of the new annual competition kicking off this week.

Among the changes the biggest will involve mystery shoppers shopping all five supermarkets in a single location each week to make each win even more meaningful, while the methodology has also been updated to score supermarkets on their self-checkout services.
