Hi............I'm probably dreaming way ahead. Big Oven giving automatic updates (like antivirus software does) into software for changing grocery store prices, including sales prices, on a weekly basis. The grocery stores would have to input their prices to a website from their computers. They already have their prices on a computer. They could charge a subscription fee for doing this. This would promote their business by free advertising of their prices. Shoppers could plan their meals around sales items, saving lots of money. Shoppers would know prices of individual items and also total menu costs. Big Oven users could drag recipes to menu--to shopping list--show individual & total prices. If you can't afford total, try a different meal. WOW.......What a dream!
