This study found that perceived trust has the strongest significant relationship with purchase intention. In other words, greater perceived trust on the online sellers motivates Gen Y to generate more intention to shop online. It showed that most Gen Y still have doubts about the online sellers since online market in Malaysia is still lacking trustworthy and reputable websites (Lim et al., 2015). Most Gen Y in this study preferred to buy from online sellers operating in Facebook and Instagram. These social networking sites are less formal and contain testimonials from previous customers, hence more trusted. This finding is consistent with many previous studies (Jarvenpaa &Tractinsky, 1999; Gefen et al., 2003; Jong & Lee, 2000; Jang et al., 2005). Since trust has proven to have a significant effect on online purchase intention, online sellers in Malaysia as well as the government should come up with some concrete measures to build strong consumer trust in order to further accelerate the growth of Malaysia’s online shopping market.
