The Book on Advanced Tax Strategies

I am so excited about The Book on Advanced Tax Strategies.  I pre-ordered a few weeks ago, and to my understanding,  it comes out today.  Does anyone know how long it usually takes to get access once it is released?  I ordered the whole package, so should have audio and digital version soon.  Just wanted to know if anyone knows how I  will get it, or how can I access it?  Thanks!
