Auction or Fixed price

[cheaver]

Confused newby. If you list an item with auction and BIN, with the same price, why would somebody bid and not just buy it? What am I missing? I will assume say if you have an item that your BIN is $15, but you would be willing to accept $10, you have an opening bid of $10?

Who has suggested this?
You are confusing yourself! Lol!
