Vacation Invitation Postcard

In today's mail, I received a postcard claiming that I won "Two Roundtrip Airfares to Anywhere in the U.S.!"  They also noted on the card:

• WE'VE BEEN GOING CRAZY TRYING TO CONTACT YOU!
• This is NOT a solicitation for a Time Share. *Certain Restrictions Apply

This might not be pitch for a time share, but I will assume that they will be trying to sell you something.  Their toll-free number is 800-979-3072.

I also found related stories about similar post cards on the 'net.
