We were saddened when we recently learned of the passing of the author of rolbe.com. Rolbe.com was a popular website that also offered an eBay Calculator and other tools to aid online sellers. According to a message on the website, the author passed away in an unfortunate accident and the site was being taken offline. Though we did not know the author personally, we believe he dedicated much of his time and effort in creating well-liked and widely used tools, and that his work will be greatly missed. We would like to convey our thoughts and condolences to those that knew him, and welcome any visitors looking for tools similar to those that he created.
