I'm seeing this:
Hmm... my "exclusive price" for this bundle which would give me just 1 title I don't already own is > than the price of that volume if purchased separately. Why would I buy the bundle? And why wouldn't the 40% off MM bracket help me get this volume for less than what I'd pay if I bought it separately?
There are some issues with the bundle pages, so it could well be that you actually get more than one book (there have been some threads about that last week) - fastest way to check would be scrolling down to the bottom and look for the stars besides the resource names.
EDIT: the James collection page says I'll get 6 new books - actually there are 19 resources with a star = new to me /EDIT
