Couponing

Yesterday I printed coupons online. I want to start couponing so I can save few dollars. I am going to ask my husband to go groceries. I like it when he go groceries by himself so it would be fast instead of 5 of us going it makes it slower..  I found few coupons online like for breakfast food like cereals, cheese, crackers etc.. I want to start couponing from wallgreens and cvs but my husband is not really crazy about it LOL..
