Another question I am frequently asked is when should one use trade instead of the auction house. On most servers, the auction house tends to have a lot posted right after peak hours, say 1am server time. Combine this with the fact that a lot of people are just sitting in cities and not really looking to the auction house. This is where trade chat dominates the auction house. Tired players are looking for conversation to take their mind off of sleeping or boredom. If you can sell effectively, trade chat will make a greater profit then the auction house outside of peak hours. A few tips to polish those trading skills might include:
Congratulations on reaching Level 120! Now that you have hit Level 120 we recommend looking at our Easy mode page and Talents section to learn how to play at max level. To get yourself prepared for the end-game content ahead, we strongly recommend this Battle for Azeroth Raiding Lexicon/Spreadsheet by Medivh. It is a gold trove of information that will help you when gearing up in Battle for Azeroth and more.
I recommend not counting on transmog sells for your monthly gametime. Its a great market, but also pretty random. You have to have the right items posted at the right moment if a player needs a certain item. If this is not the case, of course you will not sell anything to him. There are people making millions of golds a month with transmog. But they are very professional at it and it really takes a lot of time.
I'd say level this toon a bit more, maybe up to 30 or so, and see how you like the experience. If you find questing just a means to an end, maybe the guide would be a good buy. Me, I generally like questing and go to an area I'm interested in, even if it's not the most level-appropriate for me or the best way to maximize my time, so those guides aren't of much interest to me for now.
First off I wanna say that your guide truly did help. I was in my 3rd week playing the game and my friend kept loaning me money for mounts/gear things like that. I knew I had to pay him back at some point and just wanted a few pointers on how to make some gold to do that. What I got from your guide was MUCH more and I was able to pick out a few ways that helped me make enough gold to pay back my friend and even start earning some for myself. So just wanna say Thanks for all that!
2. Once you have an interested buyer, stay firm in your price. This does not mean to never make them feel like they are getting a bargain. You can subtract 5% off the price and not be hurt as long as you still make a profit! Remember this, as that 5% may not be a big deal to you, but the buyer will feel special and might buy the item for the slightly reduced price. I can not emphasize enough that this is not the same as undercutting! Do not drop every good every time or you develop a reputation as a soft seller and people take more liberties in their dealings with you. If you give someone a constant 5% discount, then they begin to want 10% and then 15% until you no longer make a profit. Discounts are used when you feel that the seller may be pulling away and you really want to just profit and move on!
