If that were the case, which I hard doubt, then the solution would be to target suppliers with enhanced consumer and business laws that make it illegal to charge different prices for the same product and volume; they should ultimately require absolute transparency for pricing up the entire supply chain, too. Shine light on everywhere the price gouging and exploitation are taking place.

I believe it’s not currently illegal for retailers to advertise and charge 2 different customers 2 different sets of targeted prices, and it should be, as retailers are nearing the capability to alter the shelf price based on the customer standing in front of it. This exploitation attack vector should be cut off before they try to get away with it (probably already are).
