Countdown's latest promotion "Domino Stars" - which features a collectable set of 50 Disney Pixar characters - has caused a frenzy around the country, with reports of pushing, swearing and underhand tactics by desperate parents wanting to get their hands on the full set for their children.
Part of the nationwide promotion involves "swap days", where shoppers are invited to visit a Countdown store at a certain time to trade the pieces. There were swap meets at stores across the country on Sunday, with another round next Sunday.
Christine Beukes wrote on the Countdown Facebook page that she had so far collected 167 pieces and spent "well over $3340" in an attempt to collect all 50.
"Needless to say I still needed 4 pieces so I went down to the Countdown in Botany yesterday to swap as advertised. Great was my disappointment when I saw a huge group of people outside under a little roof [while] rain was pouring down."
Ms Beukes went on to say that she did not exchange anything and "was shocked by the way we were chased away at 11am by an employee of the store".
