Yesterday I received my 330ml brewing bottles. I went with the Heineken green colour. I bought 72 bottles with 100 caps for only NZ$30. I found them on a site here in New Zealand called Trademe, essentially it is the equivalent of eBay.
I also invested in a good quality bottle capper, which was a bit pricey, NZ$33 at the brewcraft store, but I guess I have to put the caps on somehow.
