EBay keeps Auctions as part of their branding, but 85% or more of transactions are Fixed Price.
Auctions are only live for seven to ten days. Fixed price listings for 30 (and renew automatically).
There are more Unpaid Item Disputes with Auctions than with Fixed Price.
You can add Immediate Payment Required to Fixed Price at no charge.
Auctions work fairly well with Collectibles.
Use either Buy It Now (set BIN price at what you want to get) or Best Offer (accepting offers OVER the opening bid) to increase your chances of a sale.
Never use Reserve. If you don't want to sell for less than the Reserve, set your opening price at that point.
A low opening bid usually sells at that low opening bid.
