Erewhon is a grocery store in LA and makes its own sauces. You return the bottles back to the store and they reuse them.
Reminds me of my childhood when a milkman delivered milk to your home in bottles and you washed and left the old bottles for him to pick up. (Plus, as a kid, you would tease your friends that the milkman was your real father).
Straus Family Creamery uses glass bottles for many products, and the farmer's market refunds a $3 deposit when they're returned. The bottle caps are plastic, and there's an address where you can send them by mail.
Sending a few bottle caps by mail probably causes more environmental pollution than sending them back (after which still even more energy needs to be spent to recycle them).
