The NASB edition of
The Charles F. Stanley Life Principles Bible is $9.99 (normally $19.99). This is not a particularly good sale by itself (I've seen it as low as $3.99 in the past), but it's eligible for coupons at Kobo in the US and there's currently a contest with a generous number of >50% off coupons, up to 75% off (so you could get it for $2.50).

There's a real lack of good ebook versions of the NASB. The
Lockman edition is, quite frankly, terrible. There are no translation notes and the the formatting is mediocre (it's a straight Calibre conversion from some other format).
There are three decent versions that I'm aware of (
Charles Stanley,
MacArthur and
Life Application), but none are what I'd consider ideal. The
Charles F. Stanley and
Life Application include articles in the middle of the Bible text, which I don't really like. The
MacArthur doesn't, but each verse is on its own line rather than arranged into paragraphs like in the
Life Application.
I guess the moral of the story is if you want to buy the NASB, make sure that you check out a sample or preview first.
