I haven’t heard back from my email yet except an automated response that they received it. I will post about what I learn when I do
It could be that i wasn’t overpaying enough to trigger asking me where I want the extra money to go. this was back in my less systematic/organized days where I just randomly threw extra money at things without much purpose. Here student loan, have an extra $5. That might make a difference somewhere, right? Heh. Depending on what Sallie Mae says, I may have to do further overpayment experiments.

Ah, if I just had the magic payoff number sitting around in my bank account… lol
