B&N is offering a "Deal of the Day" half off on the Complete West WIng DVD collection,
a children's books a DTB, a CD soundtrack of Dear John and A $5.99 M Jackson Poster one day deal.
Any opinions on whether a similar dead should appear for eBooks or Nook accessories?
I wouldn't count on any nook accessories, they won't even let us use the membership discount on those.
As a general rule, stores don't run sales as appreciation presents for their customers. They usually run sales to move merchandise that they want/need to get rid of.
Funny thing about e-books: there aren't boxes of them stacked up in the back room.
B&N does have free e-book specials. Right now we've got "Free Fridays" and the weekly "pick up a code number" specials. These are often e-books by authors who have a new title in the same series about to come out—these e-books often have teaser chapters from the upcoming title (aka "Bonus Material"). In the recreational pharmaceuticals business, they call it "the first hit's free". (Personally, I think these promotional e-books are a great idea.)
As for NOOK accessories, they're just now getting them into the stores. I rather doubt that they've got a surplus of any accessories that they need to clear out.
