The first thing is to realize that it really can work, and plan accordingly. That’s not easy because so many people are disdainful of coupons, and snicker at stockpiling… so you have to ignore a lot of nonsense.
Sometimes you’ll have a shelf full of fruit and no vegetables and sometimes you’ll buy all vegetables and no fruit, but eventually it will even out. You’ll always have a well-stocked pantry at low cost, and you’ll never have to run out at the list minute and pay too much for supper.
More often than you might have thought possible, when an item goes on sale, you’ll have a coupon for it. Sometimes the coupon can be doubled or tripled, and your final cost will be half or even free.
The trick, of course, is use coupons before they expire, don’t miss any sales, and know the average cost of an item, so you know whether to stock up or pass up… so you DO have to stay on top of it… but that’s not hard, and there is help available, here:
The Couponing Mom lists sales and coupons, matches them where possible, and displays them in search-able lists, according to city and store.
Even if she doesn’t list a grocery store in your city, her lists will help because you will know what to look for by just looking through her lists.
To make the plan work best, you need a good supply of coupons, and there’s an easy way to get them… join a “coupon trading” club.
There’s lots of information there about “couponing” (look in [Files]}, and lots of people to trade with.. or, if you don’t have coupons to trade, you can find just about any you want, already clipped and sorted, for a few pennies “clipping” fee (it’s illegal to actually sell them).
Hope this helps.
