STAYKIWI
Looks like this was posted in the past and was showing as expired, it definitely isn't expired. 15% off all ferry crossings. I booked my crossing with "TRAVELTIPS" and saved 10% last night.. today found "STAYKIWI" gives 15% off but it was too late, so might as well stop others missing it!
Both working as at 16/9/22
Good luck everyone.
