Humble Bundle has been the cause of empty wallets for four years now. But the money you've lost, charities have gained, and that's a pretty awesome thing.

Known for its weekly sales, Humble Bundle is an organization that offers pay-what-you-want digital distributions for games, apps, books and more. Humble Bundle has had a hand in helping over fifty charities with a variety of causes do good through the bundles it sells. The organization takes a bundle of games, puts it on sale and allows the consumer not only pay what they want, but also designate where the money goes. You can even choose to give all your money to charity if your heart so desires.

Today, Humble Bundle is celebrating a huge milestone -- $50 million raised for charity, and it couldn't have done it without you. "We never imagined after the first Humble Indie Bundle that we might one day reach this milestone," said John Graham, co-founder and COO of Humble Bundle. "It is hard to truly comprehend the magnitude of $50 million for charity. We owe our thanks to the generosity of the Humble Bundle community -- to the content creators who entrust us with their works of art and to the consumers -- for making this possible."

Humble Bundle not only offers bundles, but also many single games in its Humble store. When you buy a game, 10 percent of your purchase goes to select charities. So, what are you waiting for? If there's an indie game you've been dying to get your hands on, head over to Humble Bundle and spend your money on more than just yourself.
