I can share a working technique, but Ill have to kill ya after that..
I kid
There are no tricks.. Sometimes you win, sometimes you lose. I snipe. Like... All the time..
Wait for the last second, not a second earlier. I have a sniping tool but its not super reliable. So I always monitor my watchlist
sometimes a seller will change the shipping fees.. Sometimes hell change the whole dam listing
Just like Hector said.. DO NOT GET ATTACHED TO THE BOOK.. Theres always another one around the corner, sometimes youll have to wait a while, but it will be there
I was looking for a Huzzah #1 for months.. Someone listed it and I sniped and lost. I wanted to hang myself... Next WEEK someone else listed it for 30.00 BIN and I got it right away
You guessed it.. The previous auction ended 3 times the amount
