(Yes, I'm aware that attendance is the "price" for the pizza, but let's just say that cold pizza can still be had for free.)
On top of that, it's not even really about the money. You don't want to feel bad about getting tricked into paying for a crap app. You'd feel like a sucker. It would be frustrating. People do all kinds of mental gymnastics to avoid feeling embarrassment and frustration --to the point that it's dangerous to call out a scammer because they are likely to get geniunely indignant and angry to avoid feeling the embarrassment of their obvious lie. Procrastination to avoid possible frustration is very, very common.
One pitch I found pretty neat goes roughly as follows.
Buy <product> 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 <marginal cost 0 infoproduct>, valued X$, as a gift from us for trying it out.
Short breakdown of it.
"Buy <product> now" - bog standard call to action
"(30|90|365) days" - if the product is any good, longer guarantees usually reduce returns, since they give more time to grow on the product and forget the guarantee date.
"feel unsatisfied" - eg. you don't even need a reason to return it
"full refund" - that's pretty d'uh now, try a 110% refund for extra excitement
"no questions asked" - eg. we're not going to hassle you for trying to use this. you will not feel stupid.
"get to keep <infoproduct>" - even if you opt out, you get something
"valued X$" - 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.Not always -- many people are shameless jerks. REI used to have a lifetime no-questions-asked return policy, but people were returning worn-out shoes and such, so they had to discontinue it.
Two counter-arguments:
People buy enticing stuff off of supermarket shelves all the time though -- things that they are not certain if they'll like them.
Lots of people who have bought and generally like an app (or so they say), still complain for its price on boards, even if it's comparable to a beer. E.g. they ask why a $2.99 app isn't $0.99 etc.
So it's not just "uncertainty".
With the app, not only are you out a few dollars, you potentially commit the sin of wasting your time by not fulfilling any desires. Though the upside is exponential (in relation to the food), so is the downside.
