Just as I anticipated, VersionTracker really would like to keep me as a Plus subscriber.

Quick update:
- 3 weeks remaining: I get a mail saying I need to renew for $25.
- 1 week remaining: new mail, now I can pay for 12 months and get 2 months extra for free (total of 14 months)
- 0 days remaining: new mail, my subscription will run out in 4 days, and I can renew for $20

Moral of the day: never renew until you have to. I, however, will let it run out and switch to MacUpdate. I think. VersionTracker does have a larger archive though, and many people seem to alert them first, or only alert them.
