Hot from my Twitter:

ESV Bible + (ESV Study Bible) App – $9.99 for the next 48 hours on iTunes!  INCLUDES ESV Study Bible notes, etc.! #fb #esv #esvstudybible

ESV Bible + app also has AUDIO (offline). VERY COOL.  Still includes all the ESV Study Bible notes.  iTunes link: #fb

EDIT: Ok, apparently one of my friends claims that the app does not have offline audio.  Hmmmmmmmm.

This is now the cheapest way to get the ESV Study Bible, if you have an iPhone, iPad, or iTouch.  Praise God!

For the iTunes link:

The only downside is that owners of the print copy of the ESV Study Bible still have to pay for this, and full price, to boot!
