This case falis within the context of the Climate-Resilience Law and invites students to question the usefulness and legitimacy of the paper-advertising catalog (also known as printed advertising) as a tool for promoting sales. More specifically, this case deals with a hypermarket located 10 km away from Montpellier, namely, Auehan Pérols. The keystone of the case is an interview with the Assistant Director of the Auchan Pérols hypermarket during which he highlights the benefits of the paper-advertising catalog as a communication tool at the local level and stands on digital alternative, the digital catalog. Other resources available in appendices will allow students to think about the advantages and disadvantages of paper and digital solutions.
