It's somewhere on listia. I've never done it and don't plan on ever doing it. I hate that listia is doing it. It's really changing what people think credits are worth and they get very opinionated about it. The information should be in customer service or the marketplace I would think
That's weird I see they have a redeem gift card option now I don't even go by credits when I lost my items I let it go for whatever and start at 499 lol best of luck to you on your auction :)
