I buy extensively from Amazon across a number of product categories. My order history shows purchases as far back as 2005 (though I cannot be sure given I remember buying things in 1998 while in college, probably on a different account). During the intervening 20 years I can count on one hand the number of products I ordered which weren’t legitimate, matched my—admittedly moderate expectations for any commercial product—or included overhyped reviews.

I’d be interested in a service like yours if I could understand how the cost would cover itself in benefits.

It makes sense on paper, if the service helps confirm legitimate reviews for you and convinces you to purchase said product, they should receive attribution revenue for helping generate the purchase.

The reality is much much messier though, because often times the people who award attribution revenue have a conflict of interest against any service that could even potentially expose bad practices happening on their marketplace.

I once worked for a popular deal site that developed a price tracking extension, a certain marketplace threatened to completely ban us from attribution revenue and we had to kill the extension over night despite our users loving it.

In my experience the problem it proposes to solve isn’t something I consider so problematic that a subscription would improve things. My experience may not be the norm, and that’s definitely a consideration I’m aware of. Still, I can’t see a reason to subscribe as such.
