Hi Ozbargainers!
I just received an email to the website that I use whenever I book a tour. Anyone who uses the link below can get €50 credit just for signing up, that equates to about $74 AUD off your tour booking. It says nothing about credit expiring so should be good for many years. Overall I think this sight is really good as it has unbiased reviews (no-one affiliated with the tour companies) and lets you easily see all the tours available for the country you are interested in. Well worth a look even if you don't sign up.
PLEASE NOTE: while I am only posting this because of the great deal for new sign ups, I of course declare that this is something of a referral page as I get some credit but only if you actually book a tour. Your credit as a new sign up, however, is guaranteed.
This was in the email: (and my referral link)
"Tour The World! Join and earn €50! Use this link to sign up with TourRadar, and you get €50 credit for your next tour booking!"
What tours?
