Am part of a Sustainable Community down here in Tas and one of our local members does it this way. Very low cost. Using beer bottles. Actually, provides his family with tomato for meals during  the entire ensuing year.

Hi Chris, great to hear from you, and thanks for adding that link. Good alternative for people who aren’t so lucky as to be gifted a full bottling kit.
