If you buy the 1$ gamepass deal, you can refund it if you cancel after a few days
this post is regarding the xbox game pass deal and i made it because i saw another post of someone that asked this same question and the comments were filled with hate-driven misinformation from angry people and none of them except one actually answered the question honestly, (https://www.reddit.com/r/xboxone/comments/1ajona1/if\_i\_buy\_the\_1\_gamepass\_trail\_then\_cancel\_it\_will/)
so the answer is actually yes, if you buy the 1$ xbox gamepass deal (that is for two weeks or a month) you can get the 1 dollar/euro back if you cancel after some days,
from personal experience i did that at least two times i got that gamepass deal for 1, then used it to finish some server-based games campaigns like diablo 3, for honor, gears of war 4 and halo infinite, and then cancelled it after 2-3 days and got them back, not sure if it works for more than half a week but up to then it does work
