Clearance item spotted this morning. Was $31.99, now $7.68.

This is the pack with dispenser - the spray refill is ~$25.
Good luck finding it. It's probably sold out by now. This was a northern Sydney Woolies.
[No info on the country of origin for this one, so it's up to you to + or - the deal on your own efforts there]
Am I the only person that thinks that an auto-spraying device, that emits noxious chemicals in your home is crazy? No wonder it's a clearance item.
