Normally $19.95/month subscription which works out to be around $718.2 for 3 years
$270 for new users or if you make a new account
$289 for existing users
Cheaper if you use a VPN for Xbox Live Gold
Step 1: Buy 3x 12 months of Xbox Live Gold (I've used EB Games because the codes were sent instantly whereas JB HIFI says up to 2 hours or longer)
Step 2: Redeem all the codes on your account, ensuring you don't accept the offer of extra months for turning recurring billing on
Step 3: Subscribe to Gamepass Ultimate for $1 which will upgrade your Xbox Live Gold 3 year subscription into 3 year Game Pass Ultimate subscription
I've just done this, and it is still working.
