Ask HN: Where does your pricing scheme come from?

Are you researching and trying to beat the competition or match the competition? Are you going with a price that makes sense for you and pricing your products and services based on your mortgage, how you feel, or the amount of work and time you put into developing your web app? Are you asking others about whether your pricing makes sense? More importantly, is your first listed pricing working for you or do you find yourself having to adjust it to a lower or higher price after your release and acquiring multiple users?
