Today I took my own paper bags to Yes! Organic Market — the one in Adams Morgan, on Columbia Road — to see if I could use them in place of the thin plastic bags supplied.
Of course I could. So I got roasted peanuts and quick-cook oats, and they were cheaper than packaged alternatives. Now, the bags — brown lunch sacks, which I had on hand — were packed in plastic, but I can reuse them to a point. (Will eventually look for paper sacks packed in paper! What a no-brainer!)
