Go to your eBay feedback page by clicking on your feedback number. Look to the right side and select view items for sale. Click that , and then copy the address of that page with all of your items listed, then paste that address into a message here on the board. For example, My ebay sales are at:

https://www.ebay.com/sch/sgobel/m.html?_trksid=p3692

Posting the link here within the message automatically turns it into the clickable link to your eBay sales page.
