Similar deal was posted here: http://www.ozbargain.com.au/node/4816 but this is $3 cheaper :)
Not sure if this is just for the Wynyard store, but the RRP is $19.95 and seems like a good deal.
I know there's a bunch of deals for cheap rechargeables but I'd rather buy this bulk load of batteries than worry about charging the suckers.
If you can't find em, they're near the counter at the front of the store.
According to Varta these batteries are better than the top of the range Energiser and Duracell too…
