copy the address of the ebay item and paste it into the box that appears when you click on the link (looks like a sloping 8)
No need for even that! Copy the ebay link from the address bar by right clicking it and dump it straight in to the txt box like this link to some wheels I'm sellin'! http://www.ebay.co.uk/itm/MERCEDES-BENZ-18-E-CLASS-ALLOY-SPORT-WHEELS-AMG-W211-S211-/262236996956
