Use the bid increment table to your advantage:
For example: You place a bid for an item with a maximum amount of $1,900. Consider raising that bid to $2,000. By doing that you will force another bidder to jump to the next level in the bid increments. In this case if you bid $1,900, another bidder would only have to go to $2,000 to beat your bid. If you bid $2,000 the next bid increment is $2,250. This forces the other bidders to bid $250 over your bid instead of $100.
