Customer commitment is also a part of key element in long-term relationships. Morgan and Hunt (1994) define commitment as an exchange partner believing that an ongoing relationship with another is so important as to guarantee maximum attempts at preserving it. Wilson (1995) also support that relationship commitment is central to relationship marketing as the most generally used dependent variable used in purchaser and retailer relationship studies. That is the perceived significance and high value of the relationship to the committed partner (Little and Marandi 2003). While, other researcher have defined commitment as an enduring desire to maintain a valued relationship (Moorman et al. 1992). Implicit in this definition is a higher degree of responsibility to make it mutually beneficial and fulfilling (Ndubisi 2007; Gundlach et al. 1995; Morgan and Hunt 1994). It seem that the commitment is an essential factor in relationship protection and in the absence of direct rewards perhaps the forecast of whether the relationship lasts (Lund, 1985). In relationship literature, it would be considered as a situation where the parties’ intentions to act and their subsequent attitude towards interacting with each other. High relationship value will affect commitment positively (Storbacka et al. 1994). Customers who are committed to a relationship with the organization are more probable delighted, but are not always delighted. For instance, a customer who has collected many frequent flyer miles with an especial airline may feel obligated to continue to support the airline although discontent, at least in the short term. In this situation, the organization at least has a chance to maintain the customer. The customer may be lost forever, if there is no commitment (Grossman 1998). Sum up, the affective commitment can generate a marketing relationship. Moreover, customer tend to have an optimistic rapport with the business they recognize themselves with, since the relationship that are create on affective commitment are more reliable (Fullerton 2005).
In online market context, customer commitment is expected to absolutely affect attitude of users toward website and their intentions to continue using the website and repurchase the product or service on the website.
