On special at masters, save $12.90 (or save $12.80 from Bunnings' labelled price, ie. can get 10% from price beat guarantee, net purchase of $10.80)
Include 3.5 litres jug and one maxtra filter.
Not sure of expiry date of the offer nor stock level with Masters. Certainly, Bunnings stocks around NSW are extremely low.
This afternoon checked that Alexandria NSW has 7.
I went in and only found 5 on the shelf. I bought two so still 3 left on the shelf. Successfully price matched with Masters Chullora and paid $10.80 x 2.
Not sure with interstate. Good luck!
