Here you can subscribe your email address for daily updates on low fares, visit a blog where the day's best finds are posted and a daily top 50 airfares.
Most people are a bit nervous about subscribing an email address to services such as this, but the front page pledges here are "we do not sell or trade email lists," and "easy unsubscribe."
You can tailor the alerts they send you to your home airport(s).
They also have a "low fare of the day" feature that is interesting if not terribly practical. One recent day's offering was Oakland-San Juan roundtrip for $290 USD, all taxes included. The entry duly noted that the fare was available only "at the height of hurricane season."
You can also type in your home airport (or one nearby) and receive a quick list of the lowest domestic and international fares at that moment in time.
Keep in mind the words "that moment in time" because a short time later, the same search could turn up much higher (or lower) fare for a specific destination.
