There is one important piece here. If you can offer something for free that "original" requires payment then that approach might work very well - at least as customer acquisition strategy. That is reason why Trello and Slack are pretty much free. As far as I remember, Gmail did the same: they offered 1GB of free email. That was so much better then my Yahoo which asked me for 9.90 a month for 250MB. So I switched. But then when you ask users to pay (to upgrade) then 1.99 vs 9.99 vs 19.99 really does not make a lot of difference. And do not be fooled by "features matters", "support matters", etc. The customer acquisition is the most important part of any (small) business (including SaaS).
