the Instant Gratification Monster rears its head again

One of the absolutely unnecessary things I'm considering spending money on when I have it to spend (hopefully in July) is upgrading my Netflix subscription so I get more than one DVD at a time. Usually I don't care, but I'm in the middle of Shogun, which is three DVDs long. I watched the first one last Friday and had to send it back on Saturday to get the second one, which I got on Tuesday and haven't watched yet. If I got all three discs at once, I could've had a marathon last Friday night.

On the other hand, if it were three episodes of a TV show, I'd have to wait a week between them, so what am I griping about?
