First time I post a deal on Ozbargain and I am not an English native so sorry if there is some mistakes…
I found this deal on Dealabs.com, a french like of Ozbargain.
Basically, book any hotel on Booking.com for a minimum amount of 225€ (338 AUD) and get 75€ (112.5 AUD) Back.
You have to click on the link and check that there is an insert below with this message:
"Book now and get € 75 back!
All you have to do is book and you'll get € 75 back after your stay! Minimum booking cost € 225."
