Here are sites on where to find the best deals on grocery stores in the county:
Martins - Thanks Livingrichwithcoupons - This states that it is for Stop and Shop but Stop and Shop, Giant and Martins are all owned by the same company and she does an excellent job. Don't really see anything super great.
ACME - Thanks FamilyFrugalFun. Some good deals of toothpaste, potatoes and General Mills products.
Food Lion - Thanks afrugalchick. Coke 2 litters are on sale for $1.33.
