If you haven't jumped on the couponing wagon yet, it's time to hop aboard. In 2010, coupon-clipping customers saved $3.7 billion, with each coupon averaging $1.46 worth of savings. If you subscribe to the paper, the Sunday edition is a treasure trove of savings. And, if you dedicate the time to plan out your meals based on the sales that week, you can save even more money.
Make sure you check out the Internet for coupons as well, and research what stores have the best prices; it may not be the same every week. You can really save money -- and time -- if you find a store that matches prices. That way, you only need to make one stop to get the best price on all of your items. The store may even offer a percent of the difference if it meets and beats competitors' prices.
Also, stock up on items when you can. If your favorite cereal bars are buy one, get one free, don't just buy two boxes. If they will keep for a while, buy as many as you can to get the greatest cost savings. You can also freeze items like beef or chicken when they're on sale. If buying in bulk adds to your savings and you can't preserve the item, find a friend to split it with. And don't forget to use the store's savings card, as well, for bonus savings and rewards.
