I am looking at a value book an I don't see any expiration date. But as Dave says, most coupons are something I wouldn't use. One coupon is for a "free work of art". Well, they have that all the time on every cruise if you attend one of the art sessions. One coupon is for rent a pair of Motorola two-way radios for the length of the cruise and receive a 3rd rental radio. Rent a set of Calaway clubs, and receive 2nd rental set free, Buy a private, 1-hr video golf lesson receive a 15-minute swing check. Purchase any "XO" Cognac and receive a free Astral "Lujos" cigar, Yep, I'll jump on that one!
. 20% off selected Spa Therapies while ship is in port. (Keyword selected), Buy internet time package Plan #1 and receive an additional 5 minutes free. There are a few more coupons. As you can see, most of them are no big thrill.
