The Reader's Digest a*s'n, INC. Unsolicited New Customer Bonus Gift Louiville, Kentucky

On August 17, 2010, I received a box stating "To be delivered by U.S.P.S. Personnel only."  It showed the originator as The Reader's Digest Association, Inc. in Louisville, Kentucky.  The box was addressed to me stating "You have been sent a free gift plus a new customer bonus gift!".  The box was printed with the words "Select Editions". The box contained a Select Editions book, an ink pen, and a small model train tank car.  Some weeks prior to receiving this box, I received an unsolicited Select Editions book in the mail.  I have never cared for Reader's Digest and did not subscribe to it and did not order the items sent.  I do not have a phone number or e-mail address to contact the Reader's Digest Association in Louisville.  Any help with this matter would be appreciated.
