Bid increments

The amount the bid increases by is known as a bid increment. Bid increments are smaller when the bid price is low, and larger in higher price brackets.

Current Price Bid Increment
$0.01 - $99.99 $1.00
$100.00 - $249.99 $2.50
$250.00 - $499.99 $5.00
$500.00 - $999.99 $10.00
$1,000.00 - $2,499.99 $25.00
$2,500.00 and up $50

 

Occasionally you'll see the bid price increase by less than the normal increment. This means that someone else placed an automatic bid just slightly higher than your maximum bid amount.
