I trade a lot on ebay and have for about 7 years. Some things are good to auction and others are not. Some things are easy to sell and others are not.
I collect and trade fishing reels. Ebay has actually created a simpler marketplace to conduct this activity.
One advantage is you have a world market for items that are available in only a few countries. I have buyers for fishing reels that could not get them any other way but on ebay. And they will pay above US retail to get them. You and I might consider it a rip off, but for those people who cannot buy them any other way, it is a bargain.
I can also buy new reels and reel parts cheaper in some countries than in the US, including shipping.
And reels that are no longer made are available and a stable market price is established. This makes it easier to trade and the market stays consistent.
So even though this idiot trying to sell a wedgie for a huge price will not succeed, many others will.
Remember, an auction sale is the highest price the market will pay, at the time. So start with a low price to genereate the most interest. If people think they can get it cheap, they will start bidding and the price will go up.
Also, only buy and sell what you know. You can easily get in over your head and waste a lot of money.
