milkum -- actually, yeah!
my wife and i got an account at www.theknot.com -- it has an area where you can register for gifts from theknot.com, and in there you can make registration requests for anything you want. you can register for and request your guests to give cash to go towards a downpayment for a house, for instance, in lieu of other gifts. no reason why you couldn't insert the cigar shop of your choice as a place where you're registered.
it's a cool site at any rate, and i highly recommend it to anyone getting ready to hitch up. mazel tov!
