You don't need to DO anything to buy, just click where it says "Reply To" shoot them an eMail to make the arangements and go buy it. Some even list a phone # You can call.
If You want to list items, You need somebody other than Me to help You.
You dont have to have an acount. When you go to reply does a screen pop up saying you need to enter your name then you do and ask for your email adress. After you do that it says you dont have an acount or need an acount? If this is whats going on I dont no why it does or what it means, all I no is I downloaded windows live messenger and mail. Problem fixed.
