If they were interested in my location they could request location data. What are the odds they are doing this to directly market products to people based on health data?
Inb4 “They already do that based on what you regularly purchase”
Of course, yes they do. This appears to be one more layer on top of it. And surely they wouldn’t share that information with the pharmacy, right?
The pharmacy can ring up anything from the grocery store. And you can pay for OTC drugs at the grocery checkout instead of the pharmacy checkout. It's the same store...
They even have gas stations. Costco is another example, but they do a lot more than groceries (automotive work, etc). Not sure why you think one store can't offer multiple services?
