I’ve decided to let the renewal of my domain name “calcylator.com” slip. The site was my web 2.0 idea that never got off the ground, the idea was simple, if you use ebay (as a seller) you need to calculate your costs, although ebay don’t hide fees from you the listing process doesn’t make it very obvious and if you sell a lot keeping track of your profit & loss is difficult… so I developed a site to track these and other costs (packaging etc).
