AP expiration date question...

Had a Brown Kitty pet on my mule from last year when they were giving out stuff for hitting level 20 on a new account.
Never took it out and it didn't have an expiration date in the cash shop.
Took it out, and the expiration date for 9/xx/2009 showed up. It died instantly.

So I'm pretty sure that timer is winding down even though you haven't touched it yet. It starts from the time the item is in your cash shop.

naw its when you first go in to cs then timer starts running. i went in to cs on 2 different days for the same account. my 20pack of apresets expire on the 3rd. my 10pack of apresets expire on the 4th.
