Yes. During the peak of covid I online shopped with home delivery from Woolworths. When I went online the next time to shop, it would show me if any of my "regular items" were on sale. It is very apparent that they track a registered customer's purchasing history.
Every time I use my Woolworths rewards card (to save money on some weekly items at a members price, to accumulate a balance that will give me $10 off my bill every once in a while, to later use at a relevant petrol station for a .4c per litre discount) I think they would have the ability to track my purchases, and where and when.
Maybe they can track EP's supermarket mushroom purchases, if she has and uses a rewards card (many people do). imo
