and 12 months for 30 bucks
Not sure if it is just me, but I went to the the tile "Free Gold Weekend" under "Spotlight" and as soon as I went to selected upgrade to gold, it gave me the option of a limited time offer to upgrade to gold for 12 months for just $29.99.
This was on the XBOX dashboard so it may come up differently for some people.
By the way, I was on Xbox Silver for one month before this.
