Don't be afraid to leave a maximum bid. Your bid will only go up by $1 at a time as the software bids for you against other bidders. If you leave a maximum bid of $50.00 and someone bids a maximum of $20 the software would push your bid to $21. If the other person tried to bid $50 you would still be the high bid because you were at $50 first. If the other person bids $51 then you would be outbid. If you have clicked on the notification box you will be notified by email that you are outbid.
