This paper explores the dierence between 'persuasion' and 'manipulation', both of which are instantiated in persuasive technologies to date. We present a case study of the system we are currently developing to foster local spending behavior by a community group | with sensitive implications for the community's sense of identity | and contrast our approach with what we would understand to be a manipulative approach. Our intention is to a) respond to anticipated critique that such a system could be interpreted as manipulative, b) present our argument for how persuasive technologies can be persuasive without being manipulative, and c) explain why, for this case study, its important that our approach be persuasive.
