Why only $30 for the Pro plan?
I've done a bunch of experimentation of price points over the years and the setup now converts by far the best. Started seeing conversions shoot up instantly upon deploying the latest pricing.
Prior to this setup it was $10, $25 and $50. No-one took out pro.
When I changed to $10, $20 and $30 it all changed. Now the majority of my paying customers are on the $20 and $30 plans.
