Apparently, Costco (http://4.bp.blogspot.com/-sZskIYUwee4/UsQe-i0dleI/AAAAAAAAAlE/p4B3AKj22RM/s1600/hardybox.jpg) is now selling a 10 book Hardy Boys box set. I presume it's 10 books from the original hardback series (RT, of course.)

Just saw this on The Unofficial Hardy Boys Homepage (http://www.hardyboys.us) today.
