Once upon a time, I got a subscription to Newsweek. Paid with a check. At the end of the year, I decided not to renew. Eventually I started getting letters from a collection agency. What?! That's right, Newsweek noticed that I "forgot" to send in my renewal, and as a "courtesy" they renewed for me. And then sent my "account" to a collection agency when I didn't pay.

Needless to say, I was done with Newsweek after that.
