It's so damn dystopian that we're even toying with such things.

But have me an idea: for whatever reason, a person consistently gets lower prices, and offers to be your shopper. You end up paying less for groceries than you would if you went, but you have to pay your shopper. So pretty much same outcome, BUT, you didn't have to do the shopping

This is why I alway bring a street urchin with me when I shop for groceries. I make sure he has a cellphone & wifi enabled. We carefully walk down the aisle side by side and the e-ink price tags start flashing. They usually settle on a price that's halfway between the personalized price for him and I.

There are a lot of positive outcomes from this technology: more revenue in the pocket of the family who own's Canada's biggest grocer & REIT, and a deeper relationship with the neighbourhood vagabonds for me.
