“…Previous studies of CRM have focused on promotional aspects, like cause-brand fit (Trimble and Rifon, 2006;Lafferty, 2007;Lee Thomas et al, 2011;Myers and Kwon, 2013), firm-cause fit (Gupta and Pirsch, 2006;Koschate-Fischer et al, 2012;Elving, 2013), ad type (Hyllegard et al, 2010;Chang, 2011Chang, , 2012Tucker et al, 2012), and ad focus (Lafferty, 2009;Samu and Wymer, 2009), but few studies have focused on CRM approach (BOGO and BOGM) and their respective application scope, not to mention comparing two CRM approaches in one study. Additionally, although there have been some studies on product types in CRM (Strahilevitz and Myers, 1998;Strahilevitz, 1999;Lafferty et al, 2004;Hou et al, 2008;Chang and Liu, 2012), they have not explored the interaction of product type and CRM approach on consumers' purchase intention.…”
