This auction is currently in the first round of bidding, which is on individual tracts only. If a bidder knows they are only interested in an individual tract it is a good idea to go ahead and begin bidding prior to combination bidding, which will start Thursday, Nov. 4th.
"Jumping the Bid" is a bidding strategy by which a bidder increases the bid by more than the next accepted bid (placing your bid at $150 when the next accepted bid is $125). This practice is used by some bidders to discourage others from bidding in hopes of acquiring an item at a lower price. There are many theories on the effectiveness of this practice and a bidder who wishes to apply it does so at their own discretion. The auction company will not lower the price of an item that has been won by a "jumped" bid with no other competing bids.
