I stand partially corrected:
The Diskbox is $80, firm, but the download is a "suggested" price of $20. You get to set your own price. If you put in $0.00, it works just fine. So basically, they're giving away the album for free download, unless you'd like to give them so cash for the hell of it. It will be interesting to see how this marketing strategy works: album for free to the masses, the hardcore fans can pay $80 for the book/cd/vinyl/singles package.
