I can use any address that is verified by listia. From their rules regarding Shipping Addresses:
"From June 1, 2011 and on, all users are to store their address(es) in the new Shipping Address feature. The saved shipping address field will become the only means through which a buyer should share his or her address with the seller. As a buyer, you can store one or more of your addresses and reuse it to tell sellers where you'd like your items shipped."
More info: "Right now we're using Google Maps to help us clean up the addresses. So far we've seen a few instances where we aren’t able to detect our users' address(es). If this happens to you, make sure you enter your correct shipping address in Step One to verify, then click on the "Need Help? Tips and advanced options" link in Step Two for more options (like PO Boxes etc). Once an address is saved, if it is still not correct (e.g., wrong zip code, city, etc), send us a support ticket at www.listia.com/help and we'll be able to fix this for you quickly."
