Let’s consider the fact, that the token price is rising again with the Virtual Blizzcon Ticket and possible Addon-Announcements for Blizzard Games. The reason the token is so cheap right now is the fact, that a lot of players bought Tokens for real money at the Shop. The more tokens are ingame, the less gold they cost. Supply and demand is the keyword here.

Special note: At 110 it's almost certainly worthwhile to go and immediately get your Heart of Azeroth and first piece of Azerite gear from the BfA opening quest. It doesn't take long and provides pretty high power levels. I'd then return to Legion quests until 111 or even 112, since the power of these items will increase your kill speed significantly over the scaled enemies of BfA content.
This is also the reason why when I read in WoW forums of people skipping guide sections, due to being too low level I'm not agree and start ranting about it: it'll be a mess syncronizing with the guide and I've seen many people complaining about missing quests or accusing the guide for being innacurate, but not realizing that was their fault since they're skipping and missing a lot of quest chain requirement. Of course this apply if you're following a guide, believe me, it's very frustrating when you remain stuck in a guide section due to the reasons I've mentioned, more than doing grey quests (but they allow to be perfectly in sync with the guide) and goiing here and there to get the pre-requisite quests.
For those interested in more details on spending wisely, and generating good cashflow, we cover a number of topics in more detail. Please note that this guide represents the accumulated wisdom of many people. You don't necessarily have to do all of these things--there is no one "right" way to make and manage money. However, these pointers will give you ideas on how to establish a firm financial foundation for your character.
Once you download the addons from the website to the downloads folder, you can right-click on the compressed (zipped) addon folders, and select "extract all". After that, you go to Windows folder, click Program Files (x86), and scroll down until you see World of Warcraft. Then click on Interface, and then select "Addons". After that, select "extract all" to transfer unzipped addon files to that "addons" folder.

The most simple thing is TradeSkillMaster. This AddOn shows you quite an amount of information in the items tooltip. In my opinion, DBRegionMarketAvg the best source. It tells me the price, an item was posted on all EU realms in the last 14 days. Why not DBMarket? DBMarket only shows you the items value from your server in the last 14 days. This value often gets manipulated. Some people start to post an item with a 500g value for 500.000 Gold on the auction house for several weaks. As a consequence, DBMarket is rising towards 500.000 Gold.  If you use DBMarket with 100% and post your item for 500.000 Gold, nobody will buy it.
