I noticed the sale signs on the windows of David Jones Sydney City store looked different today.
In the Polo Ralph Lauren section there were several 40% off signs, just in case I checked the men's Polo shirts and they were 50% off. I can't confirm how long this runs for, but I did receive email about a special 4 day sale starting today - might pay to ring first if you're planning on making a special trip.
I heard the staff say they put the 50% sign up today - may even be a wider range than just the men's polo shirts.
It is still cheaper at outlet stores, last time was 75% off.
