Sallie Mae isn't the only one that pushes your due date ahead.
Direct Loans does that too...
However they love to push the date ahead, yet still apply it towards principle after any interest is paid off. I make weekly payments online and my due date keeps getting pushed back, yet each week when I log in my balance due goes down. Your essentially prepaying that months payment, however since the interest hasn't accrued they can't apply it yet...My next due date is in November...but I'm still making weekly payments that come out to about $50 more than my monthly payment.
