If I understand this correctly, anyone can sell on Ebay.com? I have sold five items on Ebay.ca and all sold to Canadians because they didn't automatically list on Ebay.com. I want to list on Ebay.com as well. How do I do that and is there restriction...
Does anyone know the steps to check my frequency counter? I put it on the selling items but can't find it to check it. I think I did a hidden one. Thanks all. Joanne
New to this seller stuff. I wanted the ship to locations on my auction to read U.S. and Canada. I did the exclusions and kept Canada in my choices but it still doesn't show on the auction listing. How do I correct it?
