I'm a bit confused on how the Premium subscriber prizes work?

This year's Advent Calendar is giving extra gifts to Neopets' Premium Subscribers. Non-Premium users will still receive the normal number of daily gifts, but Premium users will receive extra! If you are a non-Premium user you will be able to see what Premium prize is available that day when claiming your prize and can then go subscribe to Premium and come back to claim your daily Premium prize for that day, but not any missed days.
