For those that don't know what Humble Bundle is it essentially allows you to purchase games at whatever price you want and then allows you to donate the money to various charities. The one currently going on gives your origin and steam keys for 9 origin games which include the likes of PvZ Garden Warfare, Mass Effect 2, Dead Space 2 and more to be added in a week.
If you already own some of these or they aren't your type than I'd say the $5 average fee is worth it for PvZ Garden Warfare alone. Remember it's for charity.
Also if you don't want some of the games remember you can always give them away on the forums here.
So, I figured I'd leave this here for anyone who didn't know it was going on.
