Sci-Fi & Fantasy Audiobook Bundle (MP3 Digital Download): 2 for $2, 6 for $12

Generally the way these work is there is a default "suggested" amount and a minimum. The idea is that much of the proceeds goes to a charity. (supposedly... but Humble Bundle has been running for many years and I've bought many things from them -- mostly games, but they've expanded to eBooks and audiobooks and digital comics now, also some non-game software apps).

The "minimum" in this case is $20 for the full bundle. There are lower "tiers" where you get fewer items. They used to just have a $1 minimum, but I think too many people took advantage of that thinking it was OK to just pay the minimum every time. So they went to the 3-tier system and in this case the minimum for all is $20, and the default you start with is $25. You can change it to $20 if you want, or bump it up to $30, or maybe $500 if you feel charitable! Every once in a while people do that, and it's a good thing. (will probably get some downvotes for saying that, especially since the charity this time is National Coalition Against Censorship.) Some people really seem to want more censorship these days.

it's not even close to the same quality. It'll get there.. but not yet. And the best text 2 voice services still cost $ so you aren't even really saving much for a subpar experience. Guessing you don't actually listen to audiobooks though.

Murderbot diaries is fantastic. The only oddity is I thought murderbot identified as female the whole time I read it, but the narrator is male. Took me a while to get into the male voice, but the narration is great. I've read and listened to them all. Highly recommend.
