I think this is pretty closely related to my issue here:
Except I pushed a bit further hoping Ethos could just do variable pricing like our last platform did. In which I set the price but it also allowed me to set a time for the price to change (in regards to early bird).
Though I see your specific issue is member pricing. Ethos does have the role add-on (I don’t know if DLC has ever mentioned this to you) and I believe depending on your role you will only see the price that fits your role (I’m assuming you can customize roles). But if the need is to have total control then I suppose depending how these roles are assigned, it would still be on the honor system unless you’re monitoring account creations. And also, how many roles you actually need. If it’s a small amount, it might be feasible.
