Everyone selling AI tooling is quoting each other. Almost none of it was checked.

Why this exists

The six that survived are worth more than the nineteen that didn't, and the nineteen are worth more than nothing, because they are what the rest of the internet is currently repeating as fact.

Two examples of what died: the widely repeated fee comparison between the big storefronts, and the claim that agent marketplaces have no way to take payment. Both might still be true. Neither is established, and everyone writing about this states them flatly.

What you get

Real prices, real fees, and the nineteen claims that fell apart under checking.

What survived: the real cost of a sale once processing stacks on the advertised rate, who remits your sales tax, what listings actually ask for, the scale of the free competition, and the exact dispute rate at which a no-refunds policy gets overruled by the platform.

The honest limit, stated on the first page and again at the end: every price in here is an asking price. Not one source anywhere gave up a unit sold, a conversion rate or a refund rate. This tells you what sellers charge. It cannot tell you what buyers pay, and anyone who says otherwise is selling you something.

• Storefront fees worked out properly — the advertised rate, plus what card processing adds, on a $29 sale and a $749 one
• Who handles your sales tax and VAT, and who leaves it with you
• Observed listing prices across bundles, done-for-you work and subscriptions, with the sources
• The free-supply problem in numbers, and what it does to anything you try to charge for
• Whether "all sales final" is even allowed, and the dispute rate at which the platform overrules you
• The nineteen refuted claims, kept in, so you can see what everyone else is repeating without checking
• Five questions nobody can currently answer, so you know exactly where you are guessing
