Online grocery shopping plays an important role in the current online market as the most evolving online shopping category. Despite that, consumers adopt this way of shopping quite differently across European countries. To explain such a difference, the Technology acceptance model (TAM) can be used for better understanding consumer behaviour toward habitual online shopping. This paper goes beyond and applies TAM in online grocery area based on the assumption that customers view online grocery shopping as an interaction with system respectively web page interface. The aim of the paper is to explain consumer behaviour in the domain of online grocery shopping. Structural equation modelling was chosen to determine factors influencing online grocery shopping and moreover, to find positive relationships between them.
