I would like to know where to buy fresh green coffee beans, other than online stores. Are there popular grocery stores or organic stores that sell them?

If you are in the US and a home roaster you could try sweet marias (www.sweetmarias.com). Elsewhere if you are a home roaster try your local roaster. If you re looking at commercial roasting... its a bit different of course nd will require some hard work.

I know Terroir has green coffee online, so I'm sure they sell it in store.
