Pros: Even though its not what you paid for, its still better then paying the full price for a year of xbox live.
Cons: Do not be fooled. When you order online to pickup at the store, you do not get this exact item. Not good!
The card you are given at the store is just a regular 12-month xbox live card with Halo 4 on it, but it is not the 13-month card. Maybe if you have it shipped it will be the advertised deal, but at the store they do not have these! So if you dont care about the extra month go ahead and get it, I got it when it was 39.99 so I just dealt with it.
