I think this still works buddy
Sign into your NEW or UNUSED Silver account on the first controller.
Sign into your MAIN account that is currently Silver on your second controller.
On the Dashboard, with controller #1, scroll through the ads until you see the current promotion.
Sign out of controller #1
Select the promotion with controller #2. It should now go through the process of adding the new Gold user promotion on your used account.
Congratulations! You can rinse and repeat every month to always get the new Gold member perks!


Make sure to turn AUTO-RENEWAL off so you don't get billed when the promotion is over! To do this you can go to XBOX.COM > My Account > Automatic Renewal (Turn OFF)
