> I'll make sure there's a warning email sent a couple days before any charges are applied, Since you're still figuring the best possible options and seem to be open to feedback, a reminder email two days before the charge is never enough. Ideally, it should be a few emails spread across a longer period, such as one month before, two weeks before and five days before. You could choose when and how many emails to send (bother the user), but it shouldn't be just one, and that too something that could be missed, like just two days before. FWIW, I'm not a fan of subscriptions. Since key features will be disabled unless renewed, I don't think it works as much for the benefit of the user as it does for the developer.
