Power bid allows you to expedite your rebidding when you have bid on several items in the same auction. When you use power bid, all of your bids (losing and winning) in an auction are improved by the percentage you enter in the Power Bid field. Power bidding cannot be used if any of the auction items contain price factors.
To use power bid:
On the Create Bid page, enter the power bid percentage by which you want to decrease each of your bids in the auction. Enter numbers, for example, 7.25.
Click Recalculate to preview your power bid prices. The recalculated price appears in the Price field. Because you are only previewing your power bids, your bid status does not change yet, even if your new bid price exceeds the current best bid for any auction item. Your bid prices so not take effect until you click Submit Bid.
If you want to return to your original bid prices, click Clear Changes. You can then enter a new power bid percentage and click Go to revise your power bid.
When you are satisfied with your power bid prices, click Submit Bid and review the details of your bid.
