The explosive growth of social networking sites (SNSs) has
given rise to a new electronic commerce (e-commerce) paradigm
called social commerce (s-commerce). S-commerce users employ
SNSs as a tool for collaboration to share online shopping experiences
and product- and service-related information. In addition,
s-commerce users make informed purchases and obtain the best
prices by exchanging trustworthy information on certain products
and services, which is a unique strength of s-commerce.
