Forum member emcgee found these specially marked cases of Brisk 12pk cans while shopping. Each case contains a coupon for 2x1L bottles of Brisk valid on any flavour until March 2014. This is a single coupon to get the two free bottles and not separate FPCs and is valid one per customer.
Even better, buy these towards the Pepsi $20 coupon booklet when you spend $20 promotion to maximise your savings.
What Pepsi $20 coupon booklet are you talking about? How do you get one?
