I'd heard about Tophatter ( http://tophatter.com/ ) here and there. It's a live auction site that a lot of handmade sellers use (although it is not just for handmade/vintage/supplies).
I scheduled an item for sale there. It was for a higher end (for my stuff, anyway) item that I thought might do well for Mother's Day (retail would be around $60), plus I am not going to make that style of jewelry anymore and thought it might be a good way to sell off some of my already made pieces. I have seen some items sell for a good price there. Even low quality stuff. I guess it's really unpredictable.
My item went up for auction and had lots of views/watchers. After the day of bidding passed, it sold for $9. Yes, a sterling silver locket necklace with a wire wrapped AAA pink tourmaline gemstone charm sold for less than $10.
Ugh. My advice is don't bother. I lost pretty badly, and to add insult to injury, I owe Tophatter $1 for their fee, not to mention Paypal fees.
