PurposeThe importance of food values for the post–purchase process has not been widely studied. Most previous research in this line has focused on examining either the attributes of specific food categories, without taking the corresponding values into account, or food-purchasing attitudes and behaviour. To address this gap in the research, this paper delves deeper into the influence of food values on post–purchase variables.Design/methodology/approachSpecifically, it analyses the influence of food values on satisfaction (both with the purchase and with the establishment), switching costs and loyalty. To this end, a sample of 708 consumers, collected through online questionnaires in Spain, is analysed using various descriptive statistics and causal models.FindingsThe findings confirm the influence of food values on satisfaction and that satisfaction positively influences loyalty. Switching costs were not found to moderate the relationship between satisfaction and loyalty.Research limitations/implicationsThe survey had to be completed online, and, thus, respondents needed to have an e-mail address. This influenced the respondents' profile, since many consumers over the age of 54 do not have e-mail, do not use it, or are more reluctant to complete online surveys.Practical implicationsPurchase satisfaction was not found to affect switching costs, which reinforces the idea that loyalty can sometimes be spurious. It would thus be an indicator that, as long as consumers have no other option, they will continue to shop at the establishment. In contrast, establishment satisfaction did generate switching costs. This finding could be due to aspects such as convenience, the development and maintenance of relationships with the employees, knowledge of where products are located in the store, etc. Customers may be dissatisfied with their purchase, yet still satisfied with an establishment, which could entail very high switching costs for them and, therefore, cause them to remain loyal (albeit spuriously) to the establishment.Originality/valueThis research contributes to the literature in this field by examining the influence of food values on key post-purchase variables.
