Browsing Facebook and this came up from I Know The Pilot.
After doing heaps of comparisons for international insurance costs (which I will put in the comments below for anyone thats interested) I found this similar deal, and then this comment by neil:
Appreciate the post OP but you can get 20% off Insure and Go via Groupon. No need to buy the groupon just use code groupon20. Must redeem by June 30, 2018. You can buy insurance for up to 12 months before the trip so good for trips until June 30, 2019.
So basically use that code 'groupon20' for international travel. This code works out slightly cheaper for domestic insurance.
Domestic cover for 2 weeks, 25 year old came to $33 with InsureandGo, Tick Travel was about the same and most competitors were double.
Originally I did these comparisons using my code 'HOME22', but after seeing that the 'GROUPON20' one was better I have updated it for this.
Heading to Thailand soon and compared a few providers, obviously its hard to compare as they all offer slightly different things, but based on my travels here are the quotes I found closely matching the InsureandGo Silver insurance for two weeks in Thailand for 2 people with $100 excess.
InsureandGo: $110.22
Travel Insurance Direct: The Basics $159
1Cover: Comprehensive $180 ($200 excess)
Budget Direct: Essential $161 (Last Minute slightly cheaper at $113.73, covers much less though)
Australia Post: Basic $131.40 (using TRAVEL10 code)
I did however find that the Tick Travel Insurance was cheaper with the current OFFER15 code. It came to $77 standard plan or $102 for the top plan with $200 excess.
