Free: Contests & Raffles.
I haven't received mine yet either. Good question.
The OIL notifications were mailed out the 28th of June. As I recall, the other special permit cards came out later...
Just fold it up, put it in a plastic zip lock bag, and stick it in your backpack. That's what I've always done with my permits when they were the post card size. Still was too big to cram into my wallet.
