it auto-updates to the highest bid say I put 600, you bid 555, mine goes to 556 cause I'm willing to pay more. It's now what you put down at first, it adjusts to go to who's going to put more on it. Since it's timed you can't penny raise it if you're at work, they program the auction house to raise it for you automatically up to what you bid max. so put all you're willing to spend and it won't go more than requiredHope that helps, that was one of my first problems too. Not 3DS so I'm out, but THIS IS WORTH IT still, I hope you all the best of luck, and I hope I was some help :)
