Besides making the viral message interesting to promote sharing, marketers who are
aiming to promote product sales also need a strong force to encourage message senders
and receivers to make purchase decisions. Especially in the online environment where
price sensitivity are dampened because of the in-depth price information provided by
online media, it is natural for marketers to employ pricing strategy to capture customers’ attention (Shankar et al., 1999). Arthur et al. (2009) argued that an effective pricing strategy for viral marketing should serve not only as the motivation for customers to purchase the product but also as the stimulator for customers to spread the message to their friends. However, not much literature was found regarding the pricing issue for marketing through social networks in a viral marketing setting. Thus, this study was aimed to investigate this research problem and provide a possible solution to determine an effective pricing strategy that can serve as a seeding strategy to initiate a successful viral marketing implementation. In order to propose such strategy, several studies in discount-quantity models and marketing strategies in hotel industry were reviewed as follows.
