I'm not sure I understand the question; but I'll give it a shot. A person's bid works in relation to the seller's minimum as it does to the bids of others. If the current high bid is $1,200 and the minimum increase is $50, and you bid $1,500, then your posted bid is $1,250 until someone else bids higher than that. If someone comes in and bids $1,300 then your bid automatically becomes $1,350; and the same thing continues to happen until someone bids higher than your $1,500 maximum. Similarly, if the seller's posted minimum is $1,000 and you are the first bidder, then even if you bid $1,500 your bid is going to be posted as $1,000. Then if someone comes in and bids $1,050, your bid automatically increases as before. But if no one else were to bid and you were the only bidder, then all you pay is the $1,000, even if you actually bid $1,500. Thus the first bid is always going to be posted as the same amount as the seller's minimum. Hope I haven't misunderstood your question.
