And if this sounds dystopian to you.
I anecdotally got into a CEO data conference, where leaders were discussing strategy and tactics. Biggest topic of the day was, why can't I track how many times someone sees my physical store/billboard/sign and makes a decision. Geofencing + your cellphone GPS isn't accurate enough for these guys, they want to know how long you stared at the store, what made you move in, what demographics you belong to, and how can they maximize your likelihood to purchase more stuff.
Why does this matter? People are more likely to buy more stuff in a store wandering around than on a market place where they just swap tabs to get the same thing from somewhere else.
If I can make my store front like temu to get you in and keep you there, then it's likely you'll be interested in buying more stuff you didn't know you wanted.
Generic meds vs brand meds.
Brands pay a lot for branding, and thus charge more. The formulas are moderated and regulated by the FDA, so unless you enjoy paying for ads, get the generic.
