Saw the wireless headset on sale for $49.88 at Target (Glen Waverley, Victoria). It is not advertised in the current catalogue and was not on sale at Chadstone or the City Target (as of 4th November).
I asked the guy at check why it wasn't on sale at the other Targets and he replied that some times his store is quicker on the sales than other Targets. Perhaps the sale will be filtering to the other Targets soon.
Normally sells for $69.95
