I will bid the most I am willing to pay. Say the bidding starts at $10, I'm willing to pay $25, so I'll place my max bid at $25 (my max bid is hidden from everybody else, including the seller). All I'll pay is $10 if no one else bids. If someone bids $15, I am still the highest bidder and will get the item at just over $15. This way I don’t worry about it. I place my max bid and if I win I win, if not someone else wanted it more than I did, they win. Even if someone snipes me at the last 10 sec, if they don't go over $25 I still win and get a notification that I won...or lost. Less stress.
Edit: have you ever noticed that when you place a bid and you get a notification that you’ve been out bid? That’s because someone put in a higher max bid days ago.
