How to make a link on listing to ebay store

That's pretty easy to do. When you are creating your listing, type the text you want your link to be, like "My Store" or whatever, then highlight this text and click the link tool on the description toolbar. Its the icon that looks like a globe with a chain link in front of it. Now simply add the URL for your store into the URL field that is presented and save your changes. The highlighted text should now look like a clickable link in your description. Just be careful what links you add, otherwise eBay may come down on you for violating their links policy. Though they seem to turn a blind eye to big box stores that link to their sites off of eBay.

Hope that helps!
