When you create the auction you will need to choose a starting bid.
There are some people who choose a low price, hoping to attract more
readers and more bidders and drive the price higher and higher.
Other people
choose a conservative approach: they choose a price they would like
to get, which may be a high price. This will ensure they do not
undersell the item, but they may get less readers.
Whatever you
choose as the starting price, make sure it is a price you are willing
to sell for since if the auction closes with only one bidder, that is
the price they will get.
