Just got given this by my neighbour. Definitely works in Adelaide but is meant to be Australia wide. Print it out, cut off one of the strips and get your attendant at shell to scan it for 18c a litre off your fuel purchase.
TODAY ONLY!
EDIT: Confirmed working: NATIONALLY :)
EDIT: This has got to have cost someone their job. We have cost Coles thousands of dollars already :)
ENDED: I can't believe how MASSIVE this turned out to be, first time i've ever experienced a "viral" incident and the only time i've ever started one :D
Thanks everyone for the kudos etc. I should be able to walk into any pub in Australia now and say "I am Todes Angst and I need a beer!" and get one :)
Dang. Sure coulda used this a few days ago. Fuel jumped to $1.50 yesterday. Filled up when it was still 134.
