Spreadsheet Templates, Calculators, and Calendars

I've been a big fan of DocStoc for awhile, but find myself using this more and more. From the site:

Vertex42™ is a leading provider of Excel templates, financial calculators, and calendars. We also host The Excel Nexus - The ultimate directory of 3rd-party Microsoft Excel® resources, including add-ins, templates, tutorials, and consulting services.

Contenture - Micropayment Service

A Micropayment service designed for content-oriented sites, but it works well with just about any website.

It's fully automated but you do have to pay a monthy fee (small, but important). Your site gets payments based on how often you visit. The getclicky.com folks put this together and I personally would like to see this make it in the real (interweb) world. Great idea, but there's a bunch of other players in this field.
