Great way to get the game (and a ton of other things as well) for a very inexpensive price, from what they have said on Wildstar forums it is the full retail game (standard edition) and includes the 30 days time. It will also give you access to the Anniversay goodies (but not the retail box extras)
The game can be had for a low price of basically 3.64 along with many other things.
(For current subscribers the game code is JUST FOR NEW ACCOUNTS. They have updated it to reflect this, so if you have an account already and don't want a 2nd account, DO NOT PURCHASE.)
