One specific manifestation of CSR is the solicitation of donations in collaboration with an NGO. Especially in an online environment, companies can easily control if they present donation options to consumers either before or after the actual purchase moment of their products. The aim of this paper is to investigate how the sequence of purchase and donation requests in the customer journey influences the willingness to donate to a charitable cause and the potential revenues for the seller. As theoretical frame, we use two related concepts of moral self-regulation, namely moral licensing and moral cleansing. We assume that consumers spend a higher sum on a luxury product after donating to an NGO (moral licensing) and vice versa donate a higher sum to charity after purchasing a self-indulgent product (moral cleansing). While we do not consider luxury products as morally questionable per se, prior research has shown that consumers repeatedly feel bad after purchasing a luxury item. Our results indicate that the moral cleansing effect is present in our experiment. On average, participants who first indicate their WTP for a luxury product are subsequently more prone to donating money to an NGO. We could not observe a moral licensing effect at large. Both conditions lead to comparable mean WTP measures, hence to similar total potential revenues. In general, our results indicate that both parties profit the most, if donation options are available after purchase decisions.
