Sellers use the fixed price option when they want to set a single price and eliminate bidding. Fixed price can be used for items which you know have a certain value, and whose value buyers would generally be aware of. For example, a rare coin would work best with the auction format as the market can determine what it is worth, while a new Top 40 CD is commonly known to cost around $20, so you can set a price accordingly. Fixed Price is presented as Buy It Now to buyers because they can purchase your item instantly.
Yes, in this instance, fixed price is a listing upgrade known as Buy It Now. The Buy It Now (BIN) option is an additional strategy for your auction-style listing and is your “let-it-go price”. Using the BIN option can encourage quick sales because if a buyer is willing to meet your Buy It Now price before the first bid comes in, your item sells instantly and your listing ends. However, if a bid comes in first, the Buy It Now option disappears and your listing proceeds normally via auction.
Any member with a seller account can list a single item in a Fixed Price format. To qualify for multiple item Buy It Now, you must have a minimum of 5 feedback and have been registered for at least 15 days.
To create a standard fixed price listing, simply choose "Fixed Price" on the first step of the Sell Your Item form.
To add a Buy It Now option to an auction listing, choose "Auction" on the first step of the Sell Your Item form, and then specify a Buy It Now price after you have specified your auction start price.
