Went to OW looKing for Fitbit, found this at $99. Looks like a clearance item with limited stock but maybe worth a shot. Got it at Officeworks Braddon in Canberra.
This is the vivosmart, not the vivosmart HR. It includes a 'Heart rate monitor' but not in the wristband.
Edit, not too sure which vivosmart model it is, good price either way
