This study extends the Theory of Planned Behaviour (TPB) by introducing product warranty, product information and trusted seller in the development of a theoretical model to study customers’ purchase intentions within the context of online shopping platforms.

The findings show that product warranty, product information and trusted seller are significant determinants of customers’ purchase intention of online shopping platforms. The findings are beneficial to buyers, sellers, and delivery agents
