The price freeze applies to every product in all of the nation's largest supermarkets — a group including Walmart, Carrefour, Coto, Jumbo, Disco and other large chains.

The government says it's trying to hold the next union wage hikes to 20 percent, a figure that suggests how little anyone believes the official index that pegs annual inflation at just 10 percent.
