Oh one more thing, Gevlon completely puts off spell threads in his post as being a worthless way to make gold with tailoring since so many people try to do it. This couldn't be further from the truth. The profit ranges on spell threads (including the rares) is often 20-50 gold a piece and the brilliant spellthread (requiring reputation to learn) can sell for 100-200 gold profit each.
Diversity is the key to every profession. Sell cloth, sell bags and sell threads to avoid putting all your eggs into one basket like Gevlon tends to do. It's also important to improve upon the manner in which you go about collecting materials for your crafting professions. Be sure to explore every avenue for obtaining mats before stating that a market is not profitable on your server.
Inscription Part Two
While we're on the topic of fail Goblin strategies, I recently received an email from yet another player who has taken my advice on how to deal with undercutting goblins in the inscription market... buy them out using the knowledge of which glyphs are the most popular against them.
"This is a perfect example of your buy low sell normal mantra that's worked wonders for me. I've never really invested into flipping and I'm not great at market control, but I've managed to make my money easily enough.
The first 20 or so comments on this post have been very interesting, here are my thoughts on them (too big for a comment):
It takes 45 seconds to make a netherweave bag so that's 75 bags per hour. A bag should make at least 3 gold profit each, but on many servers you can post at 48 hours and make 6-20 gold profit.
If you count afk crafting time (something most goblins completely write off as not counting towards gold per hour) at a minimum of 3 gold profit you will make 225 gold in an hour crafting 75 bags. If you make the more normal value of 12 gold per bag then you will make 900 gold per hour. Also, the demand for these items allows you to post for several gold over the lowest person at 48 hours and still sell quite often.
Netherweave cloth that goes below 6 gold a piece could be purchased by anyone and turned into netherweave bandages to be vendored for profit. I doubt cloth remains at all times at 4-5 gold a stack on his server, it sounds like a complete lie made up to simply write off netherweave bags. Every day I find people posting netherweave cloth for cheap from leveling in outland, but that doesn't make it the 100% PCT value in auctioneer nor does it stop me from buying all the cloth I see below 7 gold a stack. NOTE: I messed up here, it takes 40 cloth for the 20 bandages so it's really 3 gold per stack. Even still, seeing 4-5 gold netherweave is ridiculously cheap, you may want to consider crafting and disenchanting items from the cloth.
Bag markets MOVE quite a bit throughout the week. One day netherweave bags could go from 20 gold to 10 gold and frostweave bags could go from 40 gold to 70 gold. Materials tend to reflect this and go up and down to about the cost of a bag. The trick is hitting the peaks with bags and buying mats during the valleys.
With regards to frostweave bags and infinite dust, on some servers the dust you create on your own can be sold for more gold than you would get back using it on fostweave bags. However, getting back to diversity, it is better to not put all your dust up and instead sell some dust in the form of bags in order to get gold back faster from your initial investment. If you want to talk about absolute best use of infinite dust well enchanted vellums are the real winner but it's far better to diversify and make gold from multiple markets.
