We shop at Costco, and buy organic chicken breast and thighs, milk, bread, olive oil, pasta sauce, granola. They also have a good selection of whole wheat pasta. I don't remember seeing much organic produce, but I don't tend to buy produce there - we don't go through it fast enough for it to make sense buying in bulk. But I do remember thinking that I was pleased to see more and more organic items to pop up there each time I went. I usually go to the Pentagon City store.
