A Buy It Now (or "Fixed Price") style auction is the simplest way of listing an item on eBay.
It is when you list on item on eBay for a fixed (non-negotiable) price. When a person comes along who is willing to pay
that price for your item, they simply click the Buy Now button and make payment. There's no waiting
for the auction to end or worrying that you might not get the amount you want. It's fast, simple, convenient, and best
of all there's no extra fee to use it (normally there is an extra fee to add the Buy It Now listing upgrade an
auction). Buy It Now auctions are similar to No Reserve auctions in that
they run for a set period of time (either 1, 3, 5, 7, or 10 days). This is called your auction's
duration. If your item doesn't sell after that time is up, you will have to re-list it to have it
appear on eBay again.
