By means of an ethnographic approach, this research advances understanding of ideology, justice and consumer behavior in a food sharing context. In contrast to capitalist market exchanges, which are defined by clear rules and principles of reciprocity, the redistribution of goods in a "sharing" context is in many cases less institutionalized and thus open to contestation. We map out the interplay of different and partly contradicting ideologies in a sharing community and explain how each ideology is translated into narratives regarding the redistribution of goods. We discuss our findings in terms of their implications for the understanding of the co-constitutive nature of ideologies and their alignment.
