Have not realized that Dan Murphys sales such stuff.
State of origin NSW and OLD caps and can holders for sale. It seems to be only available for C & C either in NSW (for NSW's cap/can-holder) or QLD (for QLD's cap/can-holder).
C & C While stocks last.
Stock up, store em, go to the event and sell outdoors/near public transport for 5-10x profit profit. Clearly not worth Dan Murphys holding these a whole year or they'd keep them
