Where is the best and the most cost effective place to get my hands on 750ml talles,empty of coarse.I"m really getting into this now and want to increase my output(just got a 3rd fermenter)seems the only thing holding me back is bottles.I have been bying those Coopers plastic ones but its getting a bit costley.Any ideas anyone,just missed a bloke today in the Weekend shopper,he was getting rid of 20 doz for $100.
