Netflix has (albeit inadvertently) added a nice feature: self-returning DVDs.
While I was in Phoenix with my girlfriend, we watched at our hotel a movie that happened to top my Netflix queue. Netflix sent me the DVD before I had time to remove it.
And then it didn’t arrive. I waited patiently for three days with no sign of it, but just when I was ready to report it “missing,” it got marked “returned” and Netflix sent the next movie on my list.
(Speaking practically, I assume the label got torn off and someone at the post office, having no idea where to send it, just sealed the envelope shut and sent it back — a wise and helpful solution. But it’s more fun to think it’s just a self-returning DVD.)
