Offer a rock-solid guarantee

Give a rock-solid, iron-clad, easy-to-invoke, no-questions-asked 100% money-back guarantee.

Most customers are honest people who'd just like some reassurance that they are making a good buying decision. So they appreciate the fact that you're reversing the risk, and that makes them more likely to buy in the first place.

Sure, you will get the occasional person who exploits your guarantee. But in most markets, they are the exception, not the norm. You'll get far more sales and greater profits from your guarantee than you'll lose by those who exploit it.
