I've noticed when you bid on an item they increase ( default )by different amounts ( some increase $5, some $1, some 50 cents and some a few cents etc.) why are the default increases different for different items. Can you set default increases? I had 3 bids and only 50 cents more now.😳

You have only two bidders on your item.

One has increased his maximum bid & therefore the current bid will remain at $10.50 until a third bidder joins the fray.
