For those of you who aren't sure about the free membership with executive status posted earlier, National just mailed me a bona fide definitely good free membership offer (albeit at regular, not Executive level):

"visit emeraldclubpromos.com/spenroll. This offer expires on July 15, 2008"

So there you have it! Save $50 and don't worry that you're taking advantage of an offer that wasn't targeted at you.
