Absolute minimum price
The absolute minimum price is independent of the setting of the auction price can be used and is used for campaigns that have no fixed price (or just RTB Vickrey auction). When using a two-price auction specifying a minimum price is reasonable so as not down to 1 cent to fall (in the case that there is no two-bidder).
Note: Minimum prices are set at Insofar website or advertising space also, the highest price is used as the minimum price.
