Don't know for sure if this is the best place, but I also wanted to discuss any previous humble bundles you may have gotten. Current one is an Origin sale Currently $4.80 will get you
Dead space (Steam Redeemable)
Burnout Ultimate box (Steam redeemable)
Crysis 2 Maximum Edition (Steam Redeemable)
Mirrors edge (Steam redeemable)
Dead Space 3
Medal of Honor (Steam redeemable)
And the Sims 3 starter pack
Of course all of these can be redeemed on origin
Holy crap those are awesome games for this low of a price. Although it will raise but I doubt it'll get over $5.20.
In the past I got an indie bundle which included Amnesia: The Dark Descent, Bastion, Psychonauts (and a few others, but those are all that I care about).
