I have bought second hand bottles from Phil (calls himself the bottle bloke on ebay) in Cranbourne. He sources heaps of bottles, then sorts, de-labels, washes the bottles and then packs them in boxes ready for you to pick up. Does a fantastic job. He is a home brewer himself.
I have found his bottles to be very clean, and all that you need to do is sanitise them before bottling.
His phone number is 59964437.
He sells stubbies on ebay for 25 cents each in lots of 200, and tallies at 50 cents each in lots of 100.
He can source all sorts of bottles, both screw cap, and crown seal. Give him a sample of the bottles you want, and he can start collecting them. It does not take him long to collect several hundred (he has a great source for them). I just bought 200 Corona Extra stubbies off him, as well as 300 Carlton Colds.
Tell him that Nut Loaf Barry told you to call and he will look after you on price.
