This is noted in HELP AUCTIONS, but it bears highlighting. Bids cannot
be retracted. We will not change your bid for you. Therefore, please pay
very careful attention to what you are bidding. BID INCREASE will
increase your existing bid by the amount you specify. It does not
replace it. For example, if you bid 100 on an item, then you increase
the bid by 150, that puts your new bid at 250, not 150.

Penned by My hand on the 16th of Miraman, in the year 486 AF.
