This is NOT brain surgery, folks.
Not if you set the Buy-It-Now price right above the Starting-Bid price. For example, if the Starting-Bid price is $60 and the Buy-It-Now price is $60.01, anyone who wants to bid is just going to buy it at $60.01. Yeah, in theory someone could bid exactly $60 and force it into an actual auction which would either end several days later at $60 or cause the item to be bid up above the $60.01 level. But for all intents and purposes the above scenario represents a fixed price offering.
