Hello again. To add your address, click on your user name in the upper right hand corner. On the drop down menu, choose "edit my profile" and add your address. When you win an auction, you MUST verify your address for EACH auction you win by clicking on the auction link for the specific auction that you won and click on your appropriate correct address. Unless that is done, a seller is recommended by Listia to NOT ship to the winner. Hope this helps...Good Luck!
