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).

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!

The monthly subscription shrinkage The monthly subscription keeps shrinking in number of choices and so there are months that there are no games that I do not already own/want. I do not need more big titles but would like more options again even if it is smaller and less known titles. Also it seems that the donations to causes has dropped significantly losing that feel of contribution to a big help to these causes.

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

An Enjoyable Buying Experience Humble Bundle generally has interesting selections, be it games, books, or even 3D print models. In some ways, the quality feels not as refined as it did a few years ago, but I still enjoy checking them out. I would say I but a game or two a month. I often have to check out what charity they are donating money to; I don't agree with the leftist charities that rear their heads, but that can be adjusted.
