At Anarchy in a Jar we try and be as green as possible (e. g., local & organic fruit, eco-delivery service). Glass jars can be used over and over again--sterilized with every batch, of course. We can't reuse the flat lid--the rubber needs to be new and perfect to create a proper seal--but the metal ring and the jar are 100% reusable.
The Rejam Incentive:
If you return your jars to us we will give you a dollar off your next jar of jam. Help save the planet, one jar at a time. We already have some smart green jamarchists who have been returning their jars like good citizens (thanks, Holly).
It's easy being green. Jam on.
