"If you have questions about upgrading, it stands to reason that you already have a 1Password license." Actually, no.
I am 2 days into a 30 day trial. I like what I see so far.
Before investing a lot of time putting my passwords into 1Password, I would like to have some idea of what it might cost me to keep 1Password up to date. I am using it mostly on my PC desktop and laptop, but I will use it on my iPhone too, and maybe my iPad. $65 for a one-time purchase vs $5 a month. I prefer one-time because I hate monthly charges. What will it cost me to upgrade to the latest and greatest in 2017 or 2018? What would it cost me to upgrade now if I had purchased in early 2015? Your website won't tell me unless I enter my license number.
