Very Helpful Articles. Thanks! I heard about a new site at Church. www.mygroceryspy.com It compares prices at the top stores here in Atlanta. From what I’ve read, it updates twice a week and shows where the lowest prices are on a few hundred items. It helps me build a menu around the lowest prices. You can print out your shopping list or have it sent to your phone. (I’m not savvy enough for that though). I they are in Atlanta and Birmingham AL. then other cities.
