you search in google for some free information ebooks how to selling on ebay. Second, it depends on the kind of item you're going sell. And since it your own stuff around the house.

You can take a risk by not buying anything just register with ebay, understand their rules and list your items.

And here's the trick, when you list start the auction with $0.01 to entice people to bid. I usually list for 10 days and you can try that if you want. You also need to research some auctions related to yours to see how they listed it and what keywords they used in description.

Research auctions that have already ended.
