> that's what should be illegal: to give discounts based on whether you disclose your PII or not That would definitely help, but I think it wouldn't be enough.

Drugstores would promptly come up with some app-related trick, like "just scan this QR-code to redeem your discount", and personal info would be acquired indirectly. Legislators started to elaborate a bill recently, addressing the case of drugstores in particular, but I suspect they will end up delivering something full of breaches, just like they did in the State of Sao Paulo. Moreover, drugstores are on the spot currently, but there are plenty of companies doing exactly the same nowadays. > in the Brazilians drugstores case, it's absurd, it's like, a $400 drug sold for $300 Indeed. And I've seen even more scandalous differences already. Psychiatric drugs are the champions, in my experience.
