I've purchased these before and they seem to be ok.
Found these on the clearance rack in the centre isle at Bunnings Mentone 3 boxes left when I was there. (After I bought 6 packets)
Took them to the register told the customer service rep they were on the clearance rack, who asked her manager, who told her to sell them 1/2 price.

Not sure if elsewhere.
