I dont know what a detailed body is.
if the auction has no bids already you can add a buy it now price by clicking REVISE item
however, if someone hits the Buy it Now the listing sells to them for the BiN price.
but.... if someone places a bid on the auction, after you add the BiN, then the BiN price disappears and it becomes a normal auction and will run its course.
