Every week a couple near my local supermarket hold a yard sale in their front garden - loads of clothes, shoes etc. Full clothes racks, dozens of pairs of shoes etc. Opposite them is a Traid recycling bin. I don't have any evidence that they are nicking stuff from the bins, but I suspect they might be. It bothers me because a) people donate to charity when they could just sell the stuff themselves on Ebay and b) the money it raises goes to a good cause. But as I said, I don't have any evidence to accuse them. My DH says it's not my problem. Should I do anything?
