Besides coupons what are good ways to save on groceries and shampoo /laundry, etc.? We have a Sam's and Costco membership (Costco is a gift yearly). We are a family of 4 ( 75% of time 3 as DS is away at college). I need guidance on how to save on our groceries and daily cost of living expenses. I know it will take time but any small steps to get started would be appreciated.
