In turn, retailers can further their competitive position by coupling customers’ expectations about services with the prices charged (Wolfinbarger and Gilly, 2003 and Reichheld and Schefter, 2000). For example, in the case of PDS, Chen (2001) established that Internet retailers could actually lower the prices they charge customers so as to prime them to expect delays in order fulfillment. Online customers have also been found to be willing to tolerate protracted deliveries when they deem the retail prices they pay to be relatively low (Cao and Zhao, 2004).
