Zero-waste means shopping with less throwaway packaging, and the Bay Area is one of the best places to do it: refilleries, bulk-food shops, package-free stores and refill delivery across SF, Oakland and Berkeley.

Yes, some shops deliver refills in returnable packaging across Oakland, Berkeley and parts of SF. Check each listing for its area.
