Since our town is so small, it is just as easy to drop off your donations at the actual thrift store, but I have seen them when I used to live in Tallahassee, FL, and I thought that they were a good idea.
Also it is almost like free cycle you take them and drop them off and other come and take what they want no charge. and a few places here have clothing rooms you can get free clothes from. everything my kids out grow go to my nieces and nephews and we accept handme downs also.
