I heard this advertisement on the radio, and cannot see it mentioned on the Joyce Mayne website. 20 - 50% off everything store wide, tonight only (Monday 25th) from 6PM to 9PM. Advertisement was played on Hot 91.1, no specific stores were mentioned, so it should be all stores. I am pretty sure that Joyce Mayne is owned by Harvey Norman, so whilst everything is probably overpriced to begin with, there might still be a few good deals.
