Grocery

Does anyone have any ideas for coupons? I thought that Matt and I did a great job of eating on a budget, but after doing some comparsions at work I learned that we spend almost twice as much as some of my co-workers! CRAZY! With high hopes today I bought the newspaper, and lets just say I (totally) bummed when all I found was five coupons that weren't for diapers! Three of the five were for dog treats... I know those guys will love them, but still!!!

Any ideas on websites, papers, etc... would be great!
