i'd rather see an online tool that can be accessed from everybody's phone and presents shelf prices for all items in a certain radius, and have the government mandate participation. this will take prices down.

if i want tropicana grapefruit juice in metro detroit (or windsor, on), i would enter it in the search field and it would tell me the up to date price of the item in all stores in the region.

not participating would attract heavy fines or loss of retail license.
