I got an email about this because my sub had expired and resigned up for $133 for the year ~$11 a month instead of $17.
It seems you can also gift the yearly sub to extend your current sub i have read which is a great deal for people who use Humble regularly.
Many people say humble has dropped in quality but for slightly over $1 a game per month in my eyes its still great value.
You can also pause month to month if you don't like the offering and extend your 12 months longer.
When subbing make sure to click annual and enter the code "HOLIDAY22" when asked for coupon code.
My approach to Humble bundle these days is less about value than the time available to play all these games. Epic are giving away free games every week and Game pass and PS+ are not that expensive either.
Personally I can't justify paying anything for any game now when I have close to a hundred top notch games in my backlog already.
I'm almost looking forward to my PS+ subscription ending soon because at least my backlog will shrink a little then.
