Has that actually happened in retail stores? All I can find on the topic is about online purchases (or ordering/paying online and picking it up at the store).
To do this in brick-and-mortar, you'd have to use remotely programmable price tags and detect who is looking at what, which seems doable, but then you still run into all kinds of tough questions with no good answers. If I happen to see the price tag change from $3.49 (perhaps set for the person in front of me) to $4.49 and I put that item in my cart, which price am I getting charged at the register? And did a legal sale even occur if I wasn't aware what I would be paying? I don't think it's going to work.
