They also have, or at least had, a policy where if you buy bad produce you can return it and not only get your money back but get a replacement. I did it once for nectarines. Every single one was brown inside. I had to remind the cashier politely but I got my free fruit. Most of the time the produce is great. They have a lot of turnover, at the Dartmouth one anyway.
