becuz i saw some people always win bid so i think maybe it have tips?

I only did one auction and won, all i did was copy max gralales, paste bid repeat

You can also type in a crazy number like 4473466643 even if you have only 10000. It will automatically make your bid the next highest, and you won't be able to go over your limit. I usually add two random digits to the number that was given when I clicked the button.
And no fsh, I don't have a souizen :(

i have 100k but after i bid the number of bid will back to same price of the item:(

So it goes up by increments of ten right? Heres a hypothetical situation: Say it's at 23730 when you hit the button. Then you type in 2374089 (23740 is the number it gave you when you hit the button) even though you only have 35000 and hit enter. By then, multiple people have already bid and it's at 25830, and your bid goes to 25840, because it is the next number in the increment cycle of 10. They do this by time instead of letting us choose the amount because things would be much more expensive and people would complain.

What I do is only add 0(zero) each time I type the bid price and it automatically going to highest bid

I add like 8 zeros and wait until my timer hits 15 seconds remaining. Then I hit bid, then add 3 zeros then bid, and repeat. That's how I won a souizen.
Or you can just add like 20 zeros and wait until like 1 second left and bid. But that's risky, as your timer may be off.

What do you mean by timer, I have never seen One in the auction rooms.

stupid everyones like to buy gralat packs to out compete everyone showing off a crap ass recolor of an umbrella. everyone who bids on auctions is a scrub and i will automatically lose respect for you if you do. thanks

You get another device, say a stop watch or a phone, and hit a stop watch when you see the auctioneer say ":host_item-item_4-2" and wait until it says the amount of time in minutes that corresponds to a number in the sentence stated earlier. One of the numbers is the number of items hosted (like 2 gold Uzis for example) and the other is the time. I'm not very sure which is which though. Also, I'm not sure if everything punctuation and content wise in that example is accurate, it's just a gist: you see two numbers. One of them is usually 1 so look at the other

I still don't get it so if an admin that's hosting says :host_item-burger_4-2 should it be 4 minutes or 2 minutes?

I think the command is something along the lines of:
:host item_melee-umbrella 1 5
The first number, in this case 1, is the quantity of the item. Usually it is 1, but sometimes it's 2 for water pistols, golden Uzis, or something like that.
The second number, in this case 5, is the duration of the auction in minutes. This auction will end exactly 5 minutes after the command is processed. If you set a timer, I would bid at around 4:59 or sooner depending on your reaction time and Internet connection.

I wasn't sure, so I said to use the one that isn't a 1. Bobo explained it better than I did :P

How long do you set the timer for and should you start the timer right when the auctions first bid starts?
