The 2nd and final (hopefully) update to my original post Sallie Mae The Billion Dollar Scammer! No Online Principal Only Payment Option! and the 1st update Round 2: Sallie Mae's the Bitch.
My other issue is if you can make a principal only payment via the mail why doesn't Sallie Mae offer the a corresponding online option? I already know the answer - because the interest will accrue while the payment is in the mail increasing the amount from your payment that would be applied to interest and decreasing the amount that would be applied to principal. Geez - is this not the definition of SCAM or ASSHOLE?!!
