The
nine inch nails twitter account just announced that a very limited number of copies of the $300 Ghosts Boxed set are for sale at
the nin:ghosts website. "These had been held aside from the original run of 2500 for promotional use, but we did not end up needing them. Yes, they are signed." They may also be sold out by the time you read this. The last copy of this that sold on eBay went for $400... this is as cheap as a new copy will probably ever come. Good luck!
Update: Within a half hour, this new-old-stock of Ghosts LE boxed sets sold out.
