Hi, amme22!!! A premium listing is a listing that gets a lot more exposure then a regular listing. Up at the top of your personal listing page there is always the option to pay credits for a bold or a premium. The premium cost anywhere from a few hundred credits up to 3 or 4,000 credits, depending on how many others in your category are buying up slots for premium listing's. Say I'm browsing & am looking at a collectable, I may see your listing as other recommended items on the right hand side. Had I not necessarily been looking for barbies, I am now because I saw her & may not have otherwise. That's actually how I came accross this listing of yours!!! :) If your listing something that you feel would spark interest in bidders, if they/more could only see it , then it's really worth paying for the premium. It's shown on so many other pages & in bold letters. I hope I've been of some help, sweetie. The doll is beautiful & I'm gonna have to bid. Best Wishes!!! :)
