I'll get right into sharing my meager tips, hope someone finds them useful.
1.Fiery Brimstone mining.
Select class->lvl59 as minimum level with max left blank-> legendary->set max buyout
Maxbuyout: Find lowest price of Brimstone by seeing what it suggests when you try to sell one, get a 'feel' for it after a while. Take that price and multiply by 0.85 to get the price you can buy FB at and sell for what it cost you.
Now you know that if an auction pops up on screen, it will yield a FieryBrimstone (100%chance? seems that way.) You will also know that you can resell the brimstone and not make a loss.
If you see -anything- available to buyout, don't think...click click click buyout. /pray
If you leave it on one class you'll miss out on some deals.
Witchdoctor: 1hand, 2hand, offhand , armor. The witchdoctor seems to be able to use the most items out of any class, this is my default.
Demonhunter: offhand (quiver), 1hand (1hand crossbows), armor
Wizard: for finding legendary source etc
Monk: Armor, and I think there are legendary Monk-only weapons that can show up occasionall
I mainly stick to -Witchdoctor- cycling between 1hand/2hand/armor/offhand (finds shields).
When haggling for a price
if you're buying from traders and they pricecheck, get at least a 15% discount on the cheapest FB available at the time. Try for another 5% off due to the convenience you're providing, 'quick easy cash'. If you're selling, try to come off as slightly reluctant/hesitant to sell Attitude (don't copypaste): "They seem to be going up in price over time, maybe I should hold onto them...but what's the best price you can give? maybe you can convince me" etc "It's not much of an upgrade for me, but..." that kind of mindset.
Do not admit "omg that's awesome! I must have it!" you'll have to pay the 'wanting it' tax if you do.
Never put more in the trade window than they asked for (e.g. because you know you're getting a bargain and you instinctively want to show gratitude). They'll usually expect the same next time, or they could think it's worth more than you're offering.
2. Advertising Auctionhouse items in trade (that aren't yours and you haven't bought -yet-).
This can be a subtle & easy way to pricecheck, or make you some quick coin.
Find something you think is a bargain but aren't sure about, link it in trade for sale at a price that's [AH price divided by 0.85] if you get someone wanting to buy you can either resell or know you've stumbled upon a bargain.
Caution: Someone might figure out what you're doing, mess you around or change their mind about buying it at the last second...request an invite/invite them to party before buying the auction to resell to them because this is when they'll go 'you know what nvm' if they're going to do that. It helps to know the market, and know you're not buying -junk- because if you try and sell junk for high prices you'll get people sending you joke offers. "sure I'll take it" etc
3. The Blind commodity 'gamble'.
Have Tomeofsecrets etc in stash, try to sell one but don't click submit. This should show you the cheapest price available at that time, if it's very low like 70 per tome when it's usually 800 there -could- be a full stack of 1k tomes priced at 70.
This is the best time to buy if you're planning to buy commodities off auction, quickly navigate to the page you need and buy a set quantity out. You can test it by buying out 1, 10, 50, 100 and check that they all gave you big discounts after buying them before moving up to 500 then another 500 etc
I was fast and didn't check before seeing the price of tomes at 70g per in the 'suggested price' of my sell tab, just bought out 1k worth instantly which was reckless. I was wanting a lot of tomes anyway, so even at market price it would have been ok.
I got a full stack of tomes (1000) for 72gold per, worst case scenario? you pay Blizzard's market price listed at the top, which isn't the end of the world if you think the commodity will increase in value later on.
4. Bidding on a lot of items to salvage.
Get your breakeven price by [multiplying Exquisite-essence price by 0.85] and make a note of it.
Set search to lvl59 min for amulets/rings/follower items and sort by lowest prices, bid on the first auction with a number that gives you the profit you're comfortable with & copy that number into clipboard so you can paste it as your maxbid from now on.
Set minimum lvl to 60 for every item category that isn't amulet/ring/follower & do the same.
Have an autoclicker to send gold/items to stash, I prefer items that take up only 1 slot and you'll occasionally find a good item you can relist, salvage the rest and sell the materials. If you're fast and lucky, you can make between 50-800k per hour depending on how many get outbid, and if you find hidden treasures to resell. Used to be far more effective when tear/essence prices were higher.
Extra tip:
set max buyout as 20k at first and work from the top down, then 30k and work your way down until you reach the ones you've already bid on. 50k->40k 80k-50K etc last time I checked it was easy to bid on your own auctions without any confirmation box coming up, forcing you to pay your max bid. This is a way to ensure you're not bidding on your own auctions.
5. Fun with gems.
-Search for and buyout un-gemmed highstat items that are underpriced and gem them for resale.
-Search for gems in items that are worth more than the asking price. e.g. search for different crit% for 1handers with a socket, time consuming and not steady income but you could get lucky.
6. Sniping underpriced weapons/armor
Set max buyout to x, refresh page occasionally and with some luck you'll see an item for 90k that does better dps than all the other items on the page that are listed at 200k. Simple. Add some filters to find 70-80+ resist armor that's underpriced as soon as it's listed.
This also works for high-mainstat follower items, highdex/resist/crit/MF DH gear or anything else you can think of.
7. Profit or Dye trying.
Buyout dye listed at far below listed vendor prices that you'd need to pay to buy it, dedicate one or more slots to listing that dye until it sells for a profit. Good for if you don't have much time to play, as it takes seconds to relist it every time. With most dyes there are times when the majority of the stock expires, and yours is left as the cheapest, there's a buffer of dyes priced below yours, just wait until they're either bought out of expire. Make sure not to deal with more dye than can fit back into your stash space.
Lovely/Vanishing/Abyssal/Winter dye is quite nice to start with, lovely because it's required for an achievement, vanishing because some people like to run around looking like they're not wearing gear & winter because it's lowcost and popular. Abyssal has a higher profit margin than a lot of other dyes but has a high cost, so only works if you've got a lot of gold to start with.
Patience and fairly high pricing. (Have patience and time will be on your side. Time and -not- being lowest priced to start with, will allow your prices to be the lowest, and allow you to have the same price that you always list at.)
This is a great way to utilize idle slots, because you can always cancel your dyes to make room.
8.Filter Legendary items by stats. Edit: and make sure to put the itemlvl
e.g. set armor to all, legendary, dex:80 runspeed:10 attackspeed:6 got yourself a list of Bojanglers with dex
Works with many other legendary items and it better than searching by name, make sure to record the fastest way to find the legendaries you want through filters.
Another strat: Set max buyout and sort by lowest price, change max buyout to lower than the lowest price listed.
9. Bid on every item if it's got a very low bid, just to get an idea of what sells and for how much.
It's worth having this tie up a small amount of gold, you'll be learning a lot.
10. Sell all helmets, bracers, 1handers all at once.
It saves time because you don't need to switch between item types when price checking. Put all dex gloves together, all str gloves together etc Organization will save time if you've got a lot of items to sell regularly.
Edit: 11. Playing 7 auctionhouses at once from one account. 3 on main & hardcore/softcore on other regions.
Logout and go to options, change it from whatever it normally is to Americas, Asia, Europe and log back in.
You can play the softcore & hardcore auctionhouses for ever region this way, if most of the fun in D3 is trading/auctioneering then this will give you more slots and markets to play with.
On the HC markets, low level items with vitality can sell for 19-35k gold. lvl5 pants with vitality etc and selling vedor-bought items is so much more rewarding than softcore. You'll have the experience of starting with very little and seeing how fast you can build that into whatever 'wealthy' is for you.
Feel free to add to this, any little things you do post them.
These are just some things I do that I wanted to share and have them all in one post that I'll add to over time if I start using new methods.
-Don't- rep me (I can't eat rep). If you find anything useful, that's enough for me. Better yet, tell me what you do that works for you, and how you do it.
