Magnet Mart television advertisements feature prominently in Canberra and feature the many misadventures of the "Magnet Mart Guy" (played by actor Brendan Sloane). The slogan "Always cheaper cheaper Oi!" and its accompanying jingle were part of a well-known advertising campaign shown during the eighties and nineties.
Until 2006 Magnet Mart's slogan was "The Challenge Keeps us Cheaper", until it was replaced by "Better Prices, Better People". In January 2008 advertising was relaunched, ditching "Magnet Mart Guy" for a couple and their neighbour, Gus. The new slogan "Start Smart" (with Magnet Mart) was adopted.
