An easy $50 bucks if you are interested. No gimmicks. I am signing up for Australian Unity hospitals and extras policy and their website says they'll give a $100 gift card to the policy holder that referred you.
Ideally, I'd say Merry Christmas and keep it all, but I am poor and always looking for ways to save. Therefore, if you'd be interested in SPLITTING the money with me then PM me your name.
Cheers!
I am not with Australian Unity, but have a look at CUA, we found them to be the cheapest for our needs.
