I worked at a small, local thrift store that supported Boxers (the dogs) in rescue. Some of the vet bills for Boxers in need are very high. One year our rescue helped almost 700 Boxers. We accepted anything and everything except large appliances and mattresses because of space. Everything is sorted. Some gets taken out to the floor right away. Some gets kicked back for cleaning, if it is worth the trouble. Fabric items that are dirty or unsellable (you'd be shocked), goes to a fabric recycle company but we get pennies per pound. Glass items can be recycled also but there is a charge. Too many times we have seen people clean out their outside storage , pack it in boxes and bring in, dirt and all. We cannot sell dirt or dirty underwear. Please be picky of what you donate, consider, would you buy that? We were very grateful for what is donated but would you buy dirty underwear??????
