A lot of time people bid close to the end. Free shipping brings more credits, but a person can't always do that. Plus you're new, which makes people wary, unfortunately. I hope the auction does good for you though.
Listia is a lot of fun really once you get the hang of it. After you've shown you're a reliable seller/buyer things pick up. I've been on here five years now and for the most part it's been great. If I can answer any questions for you, please let me know.
