That was my main takeaway from skimming. I'm not a sales person, but I could see ten cents being a significant portion of the profit margin on certain items.
For what it's worth, you can score up to 5000 users per month completely free with Sift Science. So if you run a small site, there's no fee. If you run a large site, you can see for yourself whether we're saving you enough money to justify the price.
In addition, there are discounts from high volume, for pre-payment, and there's the possibility of scoring only high-risk users. If you run a web site, feel free to shoot me an e-mail at brandon@siftscience.com, and we can figure out how to make it work for you.
Just to clarify, we charge 10 cents per unique user that you query in a month, not per query. So, you can query the same user as many times as you like in a month and the cost will not exceed 10 cents for that user.
