When you are looking at your eBay item page highlight the entire address that's in the bar at the top, you can use your mouse putting the cursor in front of the www, hold down the mouse button and swipe right to the very end, you may have to swipe past what's visible to capture the entire addy. Then copy that, in Windows that's holding down the Ctrl key and tapping C. Then come over here and open a new post or click Edit on your current post, put the cursor where you want it and hold down the Ctrl key and press V. That'll paste the link in the post for you. You can test that link in the preview mode until you are satisfied and then post. Tada!
