Variation on a theme from recent posts and deals. Only applicable for expired/non current GPU users.
Purchase multiple 3 month access codes from cdkeys.com (max two per transaction) for Xbox Live Gold, then covert to Game Pass Ultimate.
Process:
Purchase 2x 3 month access codes 4 times, and 1x 3 month access code 1 time for a total of 9x 3 month codes.
Redeem each 3 month code accepting the additional month free by turning on recurring billing. After each redemeption turn off recurring billing to be given a free month for every subsequent redemeption.
This will give you Xbox Live Gold for the maximum 36 months (9x 4 months).
Select upgrade to Game Pass Ultimate from subscriptions page, whereby you will need to pay 1 month of Game Pass Ultimate (was $15.95 for me, but others may get $1 special offer).
Your 36 months of Xbox Live Gold will be converted to 36 months of GPU.
That's 36 months of GPU @ ~$4.25 / month.
It was actually slightly cheaper earlier this afternoon, so do be sure to check cost of 3 months Xbox Live Gold before purchasing. Current price should show 60% discount. Earlier it was 65%.
Isn't this more expensive than the usual methods for gaining 36 months?
