Give more to charity! I really like the variety and frequency of bundles. I've gotten dozen of books and have found some gems of games that I wouldn't have known about otherwise. And getting to donate to charity while I do all of this is a huge bonus. Humble's choices for charities are top-notch, with a few of my favorites showing up regularly. Just don't forget to adjust your donation to give more to charity!

Downloadable books at low prices I have bought digital books from Humble Bundle several times and had virtually no issues doing so. If the books are ones that would be useful or interesting to you, the value is hard to beat. All books are downloadable in DRM-free PDF format and many are also in EPUB and sometimes MOBI (Kindle).

Great software bundles I have found some incredible game assets to use, at great prices, in their bundles. I now try to always check their Software section for handy discounts.

Gives to charities, pay what you want Good idea for buying games you aren't sure you want to pay full whack for. Introduces you to indie games you might never have played and you can also donate your payment to charity. Works seamlessly with Steam, never had any issues with redeeming the keys

Humble Bundle, Always a Good Deal HB has always been very reliable and cost effective way to get deals of games, ebooks and software, and at the same time donate to charity. I have been a member of Humble Choice Classic since it's very inception, and have always enjoyed their selections. Their support staff has always been very responsive as well.
