So Boubouille revealed the key part in how i make gold in wow, Quick Auctions.
now that the secret is out, i might as well reveal how i use it in terms of Inscriptions as it was left out until next week.
Generally, inscriptions is easy to level, herbs never really cost more than 1g per herb, regardless of what level it is so you're really looking at about 5g per mill. each time i mill i get around 3-5 pigment which means an average of 8 ink per stack of herbs.
from here i'll assume you're at max inscription, even if you're not it this guide should still work(with some tweaking).
first, if you haven't yet, get quick auctions 2. then make 1 of every glyph you have and add it to an item group. once you've added all the glyphs you know (hopefully you've have all 341 glyphs) post them on the AH according to whatever guidelines you see fit.
when choosing herbs to buy on the auction house, aim for northrend herbs only because they can be traded in dalaran for the older inks( keep more stacks of ink of the sea, midnight ink, lion's ink, and Ethereal ink than of Jadefire, celestial, and shimmering)
generally, i use the following numbers:
undercut price (amount an item already posted by competitors to undercut by): 1c
fallback price (price an item is set to if it's the ONLY one on the AH): 100g
threshold price(lowest price to post an auction at--wont post any lower than this price):10s
bid percent(price set for bids as a percentage of buyout price): 90%
post cap/items per auction: 1
now i'll go over this.
if you have tried selling auctions on the AH before you should've noticed how quickly you get undercut. undercutting by only 1 copper is key in keeping the price of glyphs as high as you can keep them.
a fall back of 100g makes it so any glyphs maximum sell price is 100g. auction house trend will usually never let you get to 100g per glyph, however in those rare cases you can force the trend of an item to get to that price. for example, i took a 4 month break from the AH simply because i no longer needed gold. when i returned the prices of glyphs were cut down to around 10-15G per glyph on average (some exceptions of course). at the moment i'm up to around 30-40g per glyph on average. one specific example is glyph of rupture, generally a must for raiding rogues. when i started up again it was around 10g, i was able to bring the price all the way up to 70g per glyph because of fallback prices and undercuts. with an average material cost of 5g per glyph and an average sell price of 30g that's 25g profit or 500% profit.
threshold price of 10s is just a personal preference. i like the idea of having every glyph on the auction house, at the lowest prices. unfortunately, good glyphs like cleaving and maul (at least on my server) are selling around 10s-5g which means selling it will make me lose money sometimes and make money at other times. this is simply to ensure i have no items in my inventory when i post auctions so i can save time.
bid percent is also a personal preference. generally items are sorted out by buyout prices by default, but if you sort items by price, they are sorted by bid price. a high bid percent of 100% for example will sometimes make your competitors' items at the top of the list even though your buyout is lower. a low bid percent of 50% risks people just bidding on it which in turn may cause you to sell a glyph for an unprofitable or less profitable amount and even worse, cause you to pay a penalty when canceling glyphs.
post cap and items per auction is a MUST. you must never sell than one glyph, simply because flooding the auction house of multiple glyphs WILL lower the amount of gold it's sold for over time.
once everything is set, click cancel items in the auction tab and quick auctions will scan every item you have up and cancel any that have been undercut or any that are the only one up.
the general plan i use is simple. any glyph that sold will send me gold in the mail 1 hour later. so i go to the mailbox and make every glyph listed in my mail box then loot all my money, or if a glyph was expired or i canceled it simply loot it.
generally i can make 1000g per day spending only around 10-30 minutes (at separate times of the day, checking to see if i was undercut and also making glyphs that sold). with extra effort (checking every 2 or 3 hours) i can make around 2000-3000g per day depending on the amount of people playing that day.
quick auctions is EXTREMELY useful for making money with inscriptions. it's a good idea to buy herbs in bulk if they are cheaper than normal and mill them all with a macro like
/cast milling
/use goldthorn
/use tiger lily
use of a turbo controller (joy2key + ps3 controller) makes milling easy to afk and do something else. after a while you will even build up Snowfall ink which can be used to craft cards in hope for nobles, trade to players for ink of the sea, or make the new runescroll of fortitude (which you can keep or sell).
as a final digression, yes i registered to post this. if you're playing on destromath-us please put my inscription alt, Flonne on your whitelist if you're using my guide, even if only for a week or so.
