Xbox core to gamepass ultimate

You can use Indian codes instead, available on Amazon.in (use your uk account, add an indian address and set it as the shipping address), and unlike Turkey where you can only do 12 to 8 months, India still let you do 36 to 24 months. It's cheaper too, I put links in one of the recent deals, but it's about £7.20 per 6 months so £43.20, then whatever you can get Gamepass Ultimate for, either MS Reward points, £1 trial if you've never used it, or buy a 14 day trial or 1 month code from cdkeys etc for about £7 and that'll get you 25 months worth for about £50.

It still works but unless it's been changed again then you can only redeem 1 x 12month code
