Aldi’s ‘Like brands’ campaign had been formulated to change quality perceptions of the supermarket, but in 2013 it was apparent that more needed to be done to address the issues of range perception and social stigma. The ‘Swap and save challenge’, a campaign centring on real shoppers and the savings made by swapping their main shop to Aldi, tackled these issues head-on.
