Ahh my anxieties watching all y'all be proactive and ready your packets as soon as your 90 day window is open. My expiration is on the 18th and while I have my packet ready I figure I'll wait until Monday the 14th to send it off with certified, priority mail express. I figure so long as I have proof I've mailed it, I shouldn't have any trouble, and PME should get it to the PO box at least a day before the 18th anyways.
