Share of wallet is key metric for most businesses and grocery retailers are no exception. We recently completed a national study of grocery customers to understand their relationship strength to grocery stores they shop at least occasionally (Please see earlier posts on some of those key findings).
Digging a bit deeper we found that having a "modern and inviting" store is a key driver of a strong customer relationship, which in turn (when measured by our Relationship Investment construct) is a strong predictor of behaviors such as share of wallet.
