One-time offers based on upgrade?

It is if you have the Pro edition.

i do.

Do you know if there is a script already developed?

Yes. Go to General Options -> One-Time Offers

@jhall_3rd: This should be possible by Pro Forms in s2M Pro, I think…

Well that’s close — and that’s the feature that inspired my question. But i need something like this that is TRIGGERED by a different criteria (other than # logins):

> for members of level 2, that WERE PREVIOUSLY level 0

TRIGGER:2:https://www.whatever

Are you saying that you don’t want the offer available to those who went straight to level 2, or who upgraded from level 1?

just those that upgraded form a specific level to another specific level. In this example, L0 > L2

Then you’ll need to set to work on some customization!
