The newspaper keeps coming

I looked out the front window and sure enough, a newspaper got delivered. It's been at least 8 months since our subscription officially ran out, and initially our paper kept being delivered each day up until the end of May, but for the past 4 weeks (except for one Sunday) we've regularly gotten the Saturday and Sunday papers. I'm happy to get the paper, and if paper delivery does stop completely, we'll sign up for weekend delivery. I'm sure that my household's story of renewing only when it's absolutely necessary and seeing if the paper will arrive tomorrow is happening to others as well. For now, I'll just let it run its course, but I wonder how long the newspaper can keep this up. The newspaper must be hurting badly if it continues to deliver, and they must be hoping that we'll eventually renew.
