I have signed up as a seller but didn't proceed with the PayPal payment how can I go back to do this?
Simply log in (top right hand corner of the homepage) with the email address and password you used when you first started to create an account. You just need to then click upgrade to change your account from the free (buyer) account to a seller account. This will then take you to PayPal where you can complete the seller sign up process and pay the sign up fee. Once you have done this you will be able to start adding items for sale.
