I would really like a feature where the price dropped! Especially for long term goals… For me I’m working a lot on habit building, which should become automatic in 1-3 months anyway, so dropping the pledge amount would benefit me by letting me see my progress.
So then I could start at $90 and see it decrease as the months went on. I think it would feel really rewarding. And if I messed up, it would jump back up.
