I know it sounds plain and boring but honestly there's no other way the last second of the bid is the only way to guarantee the item... honestly.
To do this all you have to do is:
- Watch the item(actually press button watch item)
- Write down what time the bid will end.
- Set an alarm clock for ten minutes or whenever you think will be the ideal time for you to get on eBay 1 minute before the auction is over.
- Bid 30 seconds before the auction is over.
So good luck and please help me out with comments or anything. :)
