Was doing some shopping yesterday at Coles in Chapel St. , and noticed they have Cascade kits for $4.00, bags of Coopers carb drops for a measly 50c, and bags of Coopers dextrose for $2.00. Get in and fill yer boots.
A word of warning- not all the kits have their yeast sachet, and even if they do, someone has blurred/scratched off the best before dates. Still, at $4.00 a pop, you can't go wrong.
