I think this is a great example of how even in a 'free market' the notion of price transparency is easily cheated and results in behavior that is clearly anti-consumer. Much like how the push for algorithmic pricing has resulted in cartel-like behavior for apartments, we should view this the same way.

It's all so very tiresome, especially because you have to use whatever shitty app grocery stores foist upon you and/or give up your personal data in order to get the real prices on products. There were multiple times I noticed where I was being shared 1.5x to 2x for the same goods simply because I refused to give up my personal data, and eventually I relented because I needed to save the money.

Call your senator. Surveillance pricing should be illegal.
