From Auction Show:
Auction Reminder allows you to import your watchlists from eBay and receive live reminders on your desktop when they are about to expire so that you don't forget them. Prices of items are updated every 5 minutes so that you do not need to check back on eBay to keep up to date.
The application can also be used to set alerts for other daily tasks, such as a reminder to walk the dog or when your next dentist appointment is. Templates can be set to save time repeating common tasks and the slick interface can be changed with different schemes.
