I CAN SAVE you 50 percent and more on many of the supermarket items you and your family use every day.

It sounds amazing, but it's true.

I've developed the most successful system for keeping track of the thousands of manufacturers' refund offers that most shoppers never hear about.

I have the best system for organizing all the cash-off coupons you find in newspapers like this one.

My system gives me double discounts that save me 40 percent to 60 percent on products like Pillsbury biscuits, Hawaiian Punch, Wilson hams and Mellow Roast coffee.

I also get triple discounts that have actually saved me 80 percent to 90 percent on products such as Kraft mayonnaise, Ragu spaghetti sauce, Soup Starter, Cheerios and Charmin tissue.

Super-smart shopping is what I call it, and I'm going to help you do it too.

How is it all possible?

This year the big manufacturers of food and household products will distribute more than 80 billion cash-off coupons. They will also make more than 7,000 refund offers.

I have the system that will let you find, organize and use these big money-saving discounts.

Let's start with refunding.

Imagine this: After Sunday dinner, a man walks into your kitchen. He pokes around your garbage.

He pulls the label off an empty Libby's tomato juice can and hands you 50 cents. He rips the side off a box of Birds Eye frozen vegetables and gives you 75 cents.

He's not done. He finds a Butterball turkey label and hands you two crisp dollar bills. He grins when he pulls out that Sara Lee package and gives you another 75 cents.

Fantastic?

Not really, because that's what refunding is all about. You try the product and send the manufacturer a proof of purchase. The manufacturer sends you back a refund.

An experienced refunder can save more than $1,000 a year. I've done it for the last three years. It's easy when you know the secrets.

Unfortunately, most shoppers miss out on these savings because the refund forms advertising them quickly disappear from supermarket shelves.

Did you hear about the " $4 Worth of Free Groceries" refund from Dow? I got it.

You probably also missed the $3 "It Pays to Be Finicky" offer from Hunt's.

If you have been throwing away the box tops and labels that would have entitled you to these big refunds, weep now. You threw away a handful of dollar bills.

But don't cry for long. From now on I'm going to help you keep track of terrific refund offers like these. Each month the refund offers in my "Clip 'n' File" lists will add up to almost $200 worth of money-in-the-bank opportunities.

So stop fretting about rising food prices. I'm going to help you bring them way down.

Super-smart shopping is an adventure and a challenge. You'll enjoy the fun.
