 However, some major supermarkets such as Soriana, or Comercial Mexicana sell their tortillas at a lower price than the one in the agreement, and even 14% lower than the original price, reaching even MXN 5.10 per kilogram.That is interpreted by liberals as evidence that price controls, and the Tortilla Price Stabilization Pact, were unnecessary and potentially harmful for the market.Three months after the pact was signed, the Secretariat of Economy has informed that the price of tortillas was reduced in most of the country's 53 largest cities.
