Colorful charity donation bins – you might’ve seen them pop up overnight on a block near you. They are unattended, Redbox-sized depositories placed in parking lots, by fill stations, outside strip malls. You can drive up in your car and load your second-hand clothes and shoes into a large steel drawer on the front of the bin. Presumably, someone will pick the stuff up later. Painted bright green, yellow, blue, or red, the donation boxes are printed with information about the numerous causes and projects your donation will supposedly benefit.
