Sign up for WN's email, and they will send you notice when they have a sale (every few weeks a new sale). UA often matches the price, but you'd have to go to their site or another one like Expedia or Travelocity to check the price.

Sign up for AirFareWatchdog, FareCompare and others to recieve notices when prices drop.

Best place to get more info is in the sticky in Mileage Run Discussion forum. Don't worry, not only about mileage runs

Oh, and to get WN's Ding fares (if they still have them) go to their web site and install on your computer. Who knows, they may have an App for that by now.
