I have also not rented a movie in years. I had a roommate who had NetFlix, but I won't even do that. I can by movies at Wal-Mart for $5. I can buy movies online for the same.
Smallville is a show I kind of wanted to watch, but not so much I would buy or rent it. I found a used copy of the entire first season on Amazon for $2.51 (that's right - two dollars and fifty-one cents). My Amazon Prime free two-day shipping didn't count as it was through an outside vendor, but with shipping the total was still only $5.50, and contrary to my expectations (I thought I'd get a trashed copy but still watchable) it is in almost-new condition.
It would have cost me more to rent it.
p.s. These days if I even think the word "Amazon" I come to Subsim first, so Neal gets a piece of the action.
