Always look at recent completed auctions for items similar to what you're selling. You'll get an idea of the prices and the interest shown in such items.

Be thorough and very specific in your selling terms. Read the terms of other sellers.

Think twice about selling large items that can't be shipped cheaply. Buyers often bid on them, then experience deep remorse when they realize they must find a shipper and pay through the nose. Don't complicate your life by offering to find a shipper and arrange for shipping.

I'd go on but I'm getting depressed, remembering the mistakes I made. I haven't sold in over a year. Not worth the agony.

Let me take that back. It was worth the agony. I bought a nice house with the money I made. But I wouldn't do it for a second house.

Stick to items that people can get in the mail. No personal pickup, cash when they get there, tire kicking and inspection of item won, or any other ifs-ands-buts. Let buyers know that if they win the bid they must honor their bid. Specific time by which payment must be made. Questions welcome PRIOR to bid.
