Ever heard of My Cap?
by Linda Clark
This is the URL for a cap that allows one to reuse Keurig K-cups. It works great and allows you to use your favorite coffee bean. I came to your site to find a good grinder and just thought your readers might enjoy knowing how they could reuse those K-cups and save a little stress on the environment.
Looks like a neat idea, even if a little hard work. Have you tried it yourself?
