When you use Visa Checkout and use the code VISA15OFF, your Xbox Live 12 Month Gold Membership Card will drop from $50 to only $35 which is the lowest these get.
You need to make sure and add the code during your Visa Checkout in the “Promo Code” box and click “Add” to get the discount! The code will be added before you place the order, so don’t forget to do that! I did this myself and it worked!
These are going to sell out fast, so be sure you do this now!
