The cover of Scam-Proof: The Plain-English Guide to Calls, Texts, Cards and Contractors, by Della Mercer
$7.7 billion

That's what Americans 60 and older reported losing to scams in a single year.

That's the FBI's own count, and it went up by more than half in one year. Most losses are never reported at all. The people who lost that money weren't careless. They were up against a script written by professionals, and nobody had shown them the script first.

Being smart isn't the defense. Knowing the script is.

The whole guide comes down to five rules. Learn these and you're ahead of most of the calls, texts and knocks that will ever come your way.

  1. Real emergencies can wait for you to call back. Anyone who says you can't hang up is telling you something.
  2. Hang up and call a number you already have. The back of your card, a printed bill, your own contacts. Never the number they gave you.
  3. No real bank, agency or company asks for gift cards, wire transfers, cryptocurrency or cash pickups.
  4. Never read anyone a code that was texted to you. That code is the key to your account.
  5. When you feel rushed, scared or excited, stop. That feeling is the scam working.

Plain and honest about what this is

It is

  • A downloadable guide (PDF files) you keep for good
  • Large print, written in everyday words
  • Built from FBI, FTC and court records, with sources listed
  • Printable at home on ordinary paper
  • Updated free when a big new scam appears

It is not

$37 today, $37 next month. If it's a good idea, it'll still be a good idea tomorrow.

Buying this for Mom or Dad?

Good. That's who the Family Kit is for. It walks you through the conversation without making anyone feel foolish, then gives you a one-afternoon visit to set things up together: a family code word, the phone settings, trusted numbers on the fridge.

Buy it, print the phone card and the family sheet, and bring them on your next visit. That one conversation stops the two scams that cost families the most.

Questions people ask first

I'm not good with computers. Can I still use this?

Yes. You click the button, pay, and the files arrive in your email. Open them like any attachment. If you'd rather read on paper, any printer works, or a family member can print it for you.

Is it a real book I can hold?

It's a downloadable guide, so nothing is mailed. It's designed to be printed at home: large type, one idea per page.

I'm buying this for my mother. How does that work?

Buy it with your own email, then print it or forward the files to her. Start with the Family Kit; it tells you how to bring it up.

Is Della Mercer a real person?

No. Della is an A.I. host, and we're open about that. The information isn't made up: every case and number comes from the FBI, the FTC, the Justice Department or the courts, and the sources are listed.

What if it's not what I expected?

Email within 30 days and you'll get your $37 back. No questions, no hoops.

Will it go out of date?

Scams change, so the guide does too. When a big new scam shows up, buyers get the updated pages by email at no charge.

How do I pay? Is it safe?

Checkout is handled by Gumroad, a payment company used by millions of creators. You can pay by card or PayPal. We never see your card number.

Know the script before they call.
