Behind the scenes, there are default ‘minimum bid increments’ that set a minimum limit on the next bid. For example, let's say the bid increments are $10 for items under $200 and the current bid of an item is $50. You’d be able to enter any bid greater than $60.

Bid increments generally increase as the current bid of the item increases, but the nonprofit organization has final control of setting the bid increments for a particular auction.
