My TA emailed and after 3 different reservation people, got one who gave me the credit. Apparently, the postcard is to be given to friends who are first time cruisers, and they will receive (with the code REF) a video and shipboard credit ($50 for 4-7 day, and $25 for 3 day). The small print says the credit can be given without sending the video. Anyway, she was persistent and got the credit for me. Thanks to all of you. Looking forward to going next week. Coleen
