Was looking at travel insurance for an upcoming trip, decided on going with Tick Travel Insurance anyway.
Tried various promo codes, most of which have expired or gave 5% off. Found Tick10 gives 10% off. But momoj pointed out save15 which gives 15%!
Tick are one of the cheaper travel insurance providers, yet currently one of 3 policies recommended by Choice and underwritten by Mitsui Sumitomo, and they get mostly decent reviews on ProductReview, especially when you dig deeper into reviews from people who have made claims.
Expiry date unknown.
Edit: Added Offer2019 code, which is valid from 23 June 2019 to 30 June 2019 inclusive.
And credit to 2048addict - I just took the formatting from their previous deal and reused, hope that's okay: https://www.ozbargain.com.au/node/450795
