Great news ! The offer was combinable . However the Sail the Med OBC offer was up to $400 based on the grade of cabin booked so the $200 showing in my account on the app is for that offer and there is another $50 showing for the referral link offer which will change to $200 when the app catches up (as others have reported ) Got a confirmation e-mail showing $200 and $200 .
So thanks to you all for for sharing your knowledge , experience & Sailors Loot !
Thanks Chrish2 for doing the spreadsheet and updating it - please would you add my link for Irresistible Med 2nd October - https://virg.in/oGaL
Cheers
