I was able to get super dry cans 500ml x 6 x 4 for $50 at Coles online (website is a bit problematic). DON'T get the 24 carton, do the 4x6 cans. My delivery cost was only $2.45.
I tried the CHEERS20 coupon but it didn't seem to work (including adding other items into cart to bring up the price).
May not be available in QLD,SA and TAS
