How long should I keep the browser extension ‘plug-in’ installed?
Once installed at the start of the study, the browser extension will automatically work when you complete your normal online grocery shopping on Tesco.com using the Chrome browser. The study will last for 8 weeks (2 months). We will let you know when the study has ended and you can uninstall the browser extension at the end of the study period if you wish. You may also choose to keep the browser extension installed after the trial ends.
