The Online Grocery Shopping (OGS) trial – how do people shop for groceries online?


Australians are increasingly shopping for groceries using supermarkets’ online stores. However, we don’t know much about how people are doing their shopping online and how their purchasing habits might be affected by the information available on these online stores.


We are interested in understanding how purchasing choices may change depending on the information being presented.


Over a period of approximately 4 months, we will monitor your online grocery purchases. We will do this through a web-browser extension – the Online Grocery Shopping (OGS) tool. The extension cannot capture any transaction details.

Who we are looking for

Adults that:

  • Are generally healthy
  • Have high blood pressure or are currently taking a stable dose of blood pressure medication
  • Regularly purchase most of their groceries online and plan to continue for the duration of the study


  • Would be willing to shop for their groceries online for the study

We are offering up to $350 worth of shopping vouchers in recognition of your help. You will also be able to keep wireless blood pressure monitors we provide to you (valued at $179).

On this page you will find a Participant Information Sheet that provides more detail on the study, what information we will collect and how we will store it. Please read this carefully and contact us if you have any questions.
