How to save money at the grocery store

The easiest way for me to save money at the grocery store is to NOT bring my son or husband. If I shop alone I don't get as many unnecessary items. For example, at Smith's grocery store on Wednesday I bought Mini Oreos for $1.00 and Gatorade for $1.00 for Daniel. I end up getting a treat and opening it up so he will sit in the cart and be patient while I shop. Once he had the cookies he got thirsty, hence the Gatorade. My husband is almost worse than taking Daniel along. He gets junk food for himself like chips, donuts, or cookies. I hardly ever buy those items myself. He also likes to go to the magazine aisle which is something I never purchase.
