I got the reminder envelope months before I had to renew so when they first posted about needing to mail it in I just got a money order and sent it in. I was renewed a full 10 days before the original 15th deadline via good old snail mail.
I still don't see what all the state side fuss was about. International, I can understand.
At this rate, I'll probably get my Runamuck before my Runabout!
