In Online Banking Report, we've looked at online calendars as nice-to-have additions to banking websites. They fulfill a personal financial-management role by tracking and sending reminders of bill payment and other deadlines.

If you are interested in adding a calendar to your user interface, there is a unique opportunity to purchase a turn-key calendar website, that provides not only the code, done in a Web 2.0-like look, but also 40,000 monthly visitors. You could potentially pick up some customers from the existing user base as well.

The site, Kiko.com, is for sale in an eBay auction that ends on Aug. 26. Opening bid = $50,000.

Thanks to TechCrunch for the tip.
