Dynamic pricing could be coming to your local supermarket

If my local store switches to digital price tags to do this I’m just going to gather as many as I can and flush them down the toilet.
It’s a nice thought but good luck not getting caught on the 3k cameras in the store and following you to your car.
It would be a shame if your phone was infected by a malware that rewrites all the prices in the tags in your vicinity.
