Maybe I can clarify a bit
Being a Member of Humble Bundle and being a Monthly subscriber you can get the following rewards.
-5% Opt into Humble Rewards
Get 5% back to put in your Humble wallet or give to charity of your choice. You just have to opt in. Can be spent only in store if you choose the Wallet option.
-10% off for Monthly subscribers
10% off all store purchases includes games on sale as well, Must be a a Humble Monthly Subscriber.
So in short the game is $53.99 with the discount and should get around $2.50 back for the Humble Rewards.
There is always an early unlock game or games for Humble Monthly so you are not jumping in totally blind. Next months early unlocks are The Long Dark, Quantum Break and Dawn of War 3.
Other notes : Humble Monthly is a recurring charge and has to be cancelled but they do not charge until the end of the month. Giving you plenty of time to cancel.
Hope this helps a bit. I have used Humble Bundle for quite sometime now so if you have any questions feel free to ask.
If anyone signs up for monthly i would appreciate if you would use My Humble referral link
