When I was living in Australia I used to have an app which typically gives 25% discount when dining in restaurants which supports the app. It's not Entertainment Book - it's a payment app, where you must pay through the app. Many restaurants which participated don't like it and it wasn't very widely adopted but I did save a hundred with it.
Now I am considering living in Australia again but couldn't remember the name of the app. Googled a bit and found nothing - it may as well be the case that they are dead.
Liven?
