You have to remember that extreme couponing is waaaayyy different that being a savvy shopper with coupons. The extreme couponers they feature on TV are addicted to buying stuff they will probably never use in bulk, and stockpiling it throughout their house. Sure, they may find a way to buy 40 boxes of cereal for $10, but how the heck are they going to eat all that cereal before it gets stale or goes bad?
I use a website (creativecouponing.com) that is local to my area - she matches up the sale ads with the coupons (even adding links to the online coupons). It doesn't take long, and when I clip coupons from the paper I only clip what I need (I don't clip coupons for things I wouldn't normally buy).
This is probably the best thing to do. Find a regional site that will feature stores you shop at the most. For me in the Southeast, its SouthernSavers.com. She goes through the ads for all the major grocery chains here and matches up the coupons for you. And if it is a printable coupon, she will provide a link for you to print. She also has a page about how to coupon for beginners. She will also point out if something is or is not a good deal at a store and point out where you can get it for less somewhere else.
I spend about 15 minutes clipping and filing my coupons and about 15 minutes creating my grocery list. Granted, it is just DH and I and I'm just a full time student, but even if I did have a full time job and a house full of kids, I think the savings are definitely worth 30 minutes each week.
I shop mostly at our wal mart due to the low prices. I can save about 10$ a week in coupons I look at the name brand and the store brand and if i can get the name brand for less with the coupon than the store brand i buy it but other than that everything is store brand
I've found that Wal-Mart is not the best place to get the best prices with coupons. True grocery stores often double (and sometimes triple) coupon values and many will also accept competitor's coupons, which Wal-Mart does not. And their "everyday low prices" aren't always the case and, in my opinion, those "low prices" don't justify the lost savings from not doubling coupons or accept competitor coupons.
If you always shop at Aldi and buy generic brands, then you won't see a difference with coupons, because you won't be able to use them. Couponing does require you to buy name brands. But the trick is to match the coupon when the product is on sale to maximize your savings. Even better if the store is running a "buy so many and get extra $$ off your entire order" - I love sales like that! I remember once I had printed off a bunch of coupons for $.50 off Green Giant Fresh Steamers, and they were on sale at Kroger for about $1.79 each and then if I bought 10 participating items I would get another $5 my total. I ended up getting about 6 of them for $.29 each - can't buy it at Aldi or Wal-Mart for that price.
One thing I have learned is that products tend to go on sale in 6 week cycles. This means that if you kids really like Rice Krispies and it's on sale this week, it probably won't be on sale again for another 6 weeks. You'll want to buy enough to last your household 6 weeks, and then re-stock again when it goes back on sale. Knowing your food manufacturers is a good point, as well. Rice Krispies is a Post Cereal, and Post generally alternates with General Mills. So, maybe buy enough Post cereal to last 3 weeks and then stock up on General Mills for 3 weeks until Post goes back on sale if your family can get cereal burn-out.
Being a good, smart couponer is a great tool if you are trying to live on a budget. It may take a little longer than 30 minutes a week for anyone starting out, but after a few weeks you will get your routine down and it will take you less and less time each week.
