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 – that’s an amount where the bid increment increases, also called a “jump point.” 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. It may not sound like much, but it is surprising how often this works!
