There should be a National Public Pricebook where sellers are mandated to transparently provide their current prices to the government and the government displays them to the public in a readable format that updates in real-time where consumers can easily comparison shop across different retailers and suppliers.

The benefits are that consumers get low information and search costs, because they can easily look to a central database containing all the information they need for whatever product or service they want, without having to tediously drive and walk to each and every seller and scan out the individual products/services to use for comparison, for instance.

Another benefit is that it would create more efficient markets and stimulate fierce price competition.

For logistics purposes, you can require sellers use digital price tags connected to a central system and the software they use to update their price on their price tags can automatically and synchronously update their prices listed in the government's database.
