In the on-going process of retail group concentration at national and international levels, one of the most common features is multi-format merging. Such a strategy results in the valuation of the value of the acquired format and, as a rule, in the elimination of formats that operate on a small scale and/or at the same time tend to have a weak brand capital. In such a context, it can be observed that the retail group driver aims to have a single format able to generate economies of scale both internally (regarding the supplier relationship) and internally (communication, logistics, marketing etc.) in order to attain greater levels of efficiency. In reality, on numerous occasions, the substitution of one format by another initially results in a loss of value for the group driver, in that the exchange of the new format values for the recognised values (having also been chosen by the target consumer) often causes a decrease in sales with particular consequences for the commercial brand on offer. The reasons for this secondary effect can be traced back not only to the loss of a precedent value constituted by the eliminated format brand, which the consumer pursued, but also due to the difficulty for the latter to assess the value scale of the new commercial brand. In this context, the objective of this article is to verify whether the adoption of a Group store brand and the holding over of the format in the meantime is more advantageous than the pre-existing situation. It is also of particular interest to understand not only if the trade-off in question proves positive but also to see if the time and resources invested in the conversion process can be considered acceptable on assessing the advantages ex post.
