What are the benefits to Premium Membership? Also, do redeemable memberships expire?

I recently was rewarded 2 coupons for 3-months of free Premium Membership. What I want to know is what's exceptional about Premium, and if Premium coupons can expire.

No they don't expire. They are transferable to another member.

Biggest plus in my opinion is no advertising. But there are other perks also.
