Round Up for Charity?

[bryanearl]

Has anyone created a plugin that allows the customer to select a checkbox to "Round Up for Charity" during checkout? The plugin would hopefully keep track of all funds received by rounding up so that it can be sent to charities on a regular basis, like quarterly?

If not, someone seriously needs to create it because we would purchase if I can find this type of plugin.

A solution is perhaps to add a product without category and display a simple button "Round Up for Charity"
In this button you need a customfield plugin to calculate current products in the cart and add a percent of total to the cart when user add this product.
