Its only my husband, myself and a 3 year old (who doesn't eat much), but I buy multiple items when on sale and paired with a coupon. For example, a box of crackers is on sale for $2, the regular price being $3. We go through a box of crackers in about 2 weeks, so we buy a box every other week. In a span of 6 months, that means 12 boxes of crackers (with a regular price of $36). If I buy 12 boxes of crackers when they are on sale for $2 and have a coupon good for $1/2, that means I'm only spending $18 on those 12 boxes of crackers. That's a savings of $18. When you first start couponing you may feel like you are spending more than normal because you are buying in volume, when before you weren't. Once you have your pantry stocked, your weekly grocery bill we be dramatically lower. For the most part the only thing I buy on a weekly basis is milk, fresh fruits/veggies and sometimes meat. Everything else is in the pantry or in the freezer, purchased when on sale.
