And that&#x27;s exactly why guarantees are so effective for sellers. It takes that risk off the customers shoulder, and due to the &quot;Oh, it&#x27;d be embarrassing to refund this app, since that means I made a mistake&quot;, very few people actually go through with the guarantee.<p>One pitch I found pretty neat goes roughly as follows.<p>Buy &lt;product&gt; now, and if within (30|90|365) days you at any point feel unsatisfied with it, feel free to ask for full refund, no questions asked, and you get to keep our &lt;marginal cost 0 infoproduct&gt;, valued X$, as a gift from us for trying it out.<p>Short breakdown of it.<p><pre><code>    &quot;Buy &lt;product&gt; now&quot; - bog standard call to action  
    &quot;(30|90|365) days&quot; - if the product is any good, longer guarantees usually reduce returns, since they give more time to grow on the product and forget the guarantee date. 
    &quot;feel unsatisfied&quot; - eg. you don&#x27;t even need a reason to return it 
    &quot;full refund&quot; - that&#x27;s pretty d&#x27;uh now, try a 110% refund for extra excitement 
    &quot;no questions asked&quot; - eg. we&#x27;re not going to hassle you for trying to use this. you will not feel stupid. 
    &quot;get to keep &lt;infoproduct&gt;&quot; - even if you opt out, you get something
    &quot;valued X$&quot; - with a home made infoproduct, that value is pulled straight from the posterior, but gives a value anchor

And suddenly that 3000$ product seems less risky than a 2$  app.
