I loved going to my local supermarket as they used to play a song every five minutes with the lyrics "Down down prices are down". Man I used to get so happy and load my trolley. Now they've replaced it with "There's no freshness like Cole's freshness" which just doesn't cut it for me. IGA is great, they often play Bowie which really suits the older shoppers - old lady on a walker joining in with "where were the spiders when the fly tried to break our balls".
Aldi doesn't have music, Hmm maybe Australians might dig the Horst Wessel song ....
