The local supermarket has taken to not marking prices on
items on the shelf, but rather marking the shelf.  When you
go to the checkout line, the scanner on the cash register
looks up the bar code on the item and finds the price.

They do have some incentive to get it right though.  Prominently
posted near each cash register is a sign proclaiming that if an
item scans higher than the posted price, it's free.
