If we didn't live so close to Eastern Market, we'd be ordering from Arganica pretty much every week. If you consider yourself a locavore in DC, they are the best source for a lot of the more difficult items to source at your local farmer's market, and the flour you can get from them is out of this world. Don't even get me started on the yogurt with the layer of cream on top they have. Arganica is a local business which is like a meta-CSA - you get local yumminess, what you order, delivered to your door, and support a local business who's changing the way you interact with your food. It's made of win.

And if you also support another local DC business, http://www.dealsfordeeds.com/ (think Groupon for Good), you get a 3 month membership for $40 - half off! Try it. You'll like it.
