Well,first thing you can and need to do for succesfull sell is good advertising.
Advertise your ECA and your products on every place you can- on social network (like facebook, pinterest, tweeter) , on free websites, on local TV or radio...
Next stuff you can do is to send e-mail to all your member connected to your ECA when you have new items listed, or when you have some discount on products .
Anyway, I wish you good selling and big income from your store... :-)
