[NSW] Brita MicroDisc Filter 3 Pack $6 @ Woolworths Wolli Creek

Hi,

Second time posting a deal so please be kind.
Yesterday I went to my local Woolworths to purchase the Brita Microdisc filter which is normally priced at $15. To my surprise when I paid for it I only had to pay $6 for the pack, which is a whopping 60% discount. Went back and bought a few more. Not sure if this is applicable to other Woolworths or just the one in Wolli Creek.
