Which option / version should I purchase in order to make a page a 1 time only view?
You will need a different plug-in, namely JUser BestBefore, either Premium or Business edition.
The JUser BestBefore plug-in includes the option to disable a registered account upon 1st log-in, which means that once user has logged out from the first session, he/she cannot log-in again. This is not the same as "page 1 time view" but comes very close.
The standard freeware edition does not have this option.
Please see the JUser BestBefore product info for more details (link to J25 version is here).
