I saw a few of those around, the price varies a lot. The ones targeted at making a landing pages with a signup form wanted a good deal of money per month (I don't recall exact numbers, well over $30 a month, I think one of them wanted $200 up front to get started). They typically include hosting as well, which sorta makes sense as soon as you add the least bit of interactive elements (e.g. form submissions), they want to make it super simple to get up and running.
