It's basically a live online auction - each item goes up for auction with a fast timer on it - you set the bid on your item, it goes up, you watch people bid, and can explain what you like about it, marketing it while people bid.
It's pretty nifty idea, I have an item up there for my first auction tomorrow - but I registered and watched a few before I decided to try it. It's pretty fun, and very fast. You're not going to watch your item stagnate.
The nifty thing is - it doesn't cost anything to list it, so if your item doesn't sell, no worries...you can just list it again in another auction. They go through how to use it and what to expect when you register - it's really user friendly.
As you sell one or more products, you can add more and more. There are quite alot of categories, also, so if you prefer to list in "high end" or just normal, you can. There are also supplies auctions (you can find stuff and buy things WAY cheaper there than online at wholesale)
**OI! you beat me to the explanation! Yours is better :D**
