B&H has a number of HCSB Bibles on sale. These have been on sale before, so I'm only going to list a few. The easiest way to see the full list is to go to the
"eBooks on sale" page at Christianbook and then click "Bibles" on the left. Inexplicably, these are slightly different prices at different stores.
The
Mission of God Study Bible is $.99.

If you just want a copy of the
HCSB, it's always been free at pretty much all ebook sellers, but it's downloadable as a DRM-free epub straight from B&H Publishing's servers
here. If you've got a Kindle, it's probably easiest to grab it from
Amazon. The free "Digital Text Edition" doesn't have footnotes, but the "Digital Reference Edition" (normally $5.99, but $2.99 right now) has them, as do all of the Study Bibles.
"Always Free" Bibles
While I'm at it, it's been a while since there's been an updated "always free" list of Bibles and such. Since I had to look up the link for the HCSB, here is the rest of my personal list. I didn't include the ones already in this year's thread (the New Life Version and Jubilee Version), but here's the rest of my list. I normally don't make disclaimers, but some of the stuff here isn't exactly orthodox and the definition of "Christian" is pretty broad.
The
ESV and
ESV Global Study Bible are always free from
Crossway as DRM-free epub and mobi.
The
Mormons have all of their Scripture (
Book of Mormon,
Doctrine and Covenants,
Pearl of Great Price and the King James Bible) available in electronic (epub, mobi, PDF and audio) formats
here. You can also find all sorts of other LDS publications by navigating their site (unfortunately, they don't put it all in one place). If you're interested in a general history of the Mormons, I recommend
Church History in the Fulness of Times.
Jehovah's Witnesses have their own Bible translation, the New World Translation. The
original translation was completed in 1984 and it was
significantly revised in 2013. You can also download
magazines and select
books in various formats. Their entire library (text-only) is also online
here. Their sort of door-to-door manual (which many Witnesses have bound together with their Bibles) is
Reasoning From the Scriptures.
The
Geneva Bible in a modern spelling edition is available for free download from
Kirk Cameron's site. It's PDF-only, but it's really nice, especially if you're into the history of English Bible translation.
The "Congregation of YHWH", which seems to be a sort of Jews for Jesus organization, has its own Bible translation. The
Hebraic Roots Bible is available in several formats
here.
Mary Baker Eddy's
Science and Health with Key to the Scriptures can be downloaded as a PDF
here. I happen to know that the PDF linked there is the "official" edition because it used to be available from the
Church website and "diff" says the files are identical. I normally don't link to unofficial sources, but this book is truly in the public domain (its text is in all ways identical to my copy of the 1910 edition), so I'm pretty sure it's legal to download, at least in the US (the UK has a "typesetting" copyright that might apply). The only weirdness is that the Christian Scientists have trademarked the cross and crown icon, so make sure that whatever you do with it doesn't dilute the brand

.
Free Creationist Books
Answers in Genesis and Master Books have a
creationist forum that has rather fizzled. Shortly after they created it, they would occasionally post free books to generate traffic. The original pages are gone, but I kept copies of the links and most of them still work. Until someone notices and removes them completely from the server (they've been there several years), they can still be downloaded.
These are all PDFs.
Frozen in Time by Michael Oard
Flood Legends by Charles Martin
Global Warming and the Creator's Plan by Jay Auxt and William Curtis
The Lie: Evolution by Ken Ham
Creation Facts of Life by Gary Parker
In Six Days: Why Fifty Scientists Choose to Believe in Creation
The Great Dinosaur Mystery Solved! by Ken Ham
Defending the Faith by Henry Morris
Biblical Creationism by Henry Morris
Toward the end, they finally got around to posting some other formats.
Men of Science, Men of God by Henry Morris
PDF epub mobi
The Beginning of the World by Henry Morris
PDF epub mobi
If you
sign up for the New Leaf Publishing Group, you get a couple of free creationist books (currently
Buried Alive by Jack Cuozzo and
Six Days: The Age of the Earth and the Decline of the Church by Ken Ham).
Finally, I don't recall seeing this one posted, but you can download a PDF of
The Evolution Cruncher by Vance Ferrell. It's a nearly thousand-page creationist screed that's punctuated with random fonts, italics and underlining, like a creationist
Time Cube. Now I can retire my yellowed paperback that I found in a used bookstore some ten years ago.
