The cheapest I could find the other day was from Choo Chiang Marketing. The shops in balestier are much more expensive, like 50% more expensive The price for the Clipsal Metro I got the other day: 1 gang switch: $12 2 gang switch: $22 3 gang switch: $32 I forgot the others. All prices before GST, and it's been a few months, so it may have changed
