You need to download the Rewardz App and then it tells you that it will give you $5.20 credit for free to buy a Tall Coffee or whatever else you want. You DO have to register your credit card details with Muzz Buzz though which they keep on file which will turn some people off!!!
I saw this deal advertised on a bus, and just tried it out and got my free coffee (with some difficulty - you can read my experience below and decide if it's worth the effort for you!)
I can't find any T&C or details for this promo online. There's a chance it's WA only and not Australia wide, but I doubt it. Please could others confirm whether the offer comes up on their App when you download it (the offer will appear before you add your CC details, it just won't work until you do).
(1) In the rewards app, you will first need to add your credit card details otherwise when you click 'Claim Now' on the freebie it will come up with an error. The app doesn't make this clear. It sends you an sms verification code as part of the set up of your credit card.
(2) You'll be able to click 'Claim Now' on the offer (it's really obvious in the app) at the front of the coffee line. A screen comes up giving you instructions to tell the staff 'I'll be paying with the app' and that they may need your name and the transaction number.
(3) The details will come up on the store's computer. At this point the staff got confused and claimed it wasn't working and tried to get me to just pay for the coffee, which I refused. Eventually they clicked something and gave me my coffee.
(4) I immediately got an email with a receipt for $0.00, stating that my credit card had been charged $0.00.
