I just signed up for Premium. Do I get a Premium Collectible item?

New subscribers are awarded the previous Premium Collectible as soon as the new subscription is processed. For example, if you subscribe on May 3rd, the previous collectible (which would be April 15th's item) will be placed in your inventory immediately (in the NC section) and then you'll be awarded the next collectible (May 15th's item) with everyone else when the time comes.
