Although you usually don't want to buy items to sell from vendor, some items can be sold for much more than you pay for them from the vendor. There are a few reasons people will buy a vendor item for a higher cost at the AH. They vendor may be hard to get to, the recipe only sells in limited stock, or the buyer simply may not know where the item is from.
To use it as a bag-space creator, simply send excess items to the bank alt whenever you're near a mailbox for a low price of only 30 a slot. Even if you accidentally send the wrong item to the bank alt, it can be returned-to-sender for free. It's very quick, due to the fact that sending mail between characters on the same account is always instant.
When hovering over an ability, the tooltip will tell you whether or not that attack is weak or strong against certain pet types. Additionally, you can hover over the opposing team's pets and view their attacks during combat. This will be important since it’s a good idea to pit a pet that's strong against the opponent's pet who's vulnerable to that type.
But the system offers a painful and mindless grind. At worst, it feels like a cheap and artificial wall blocking you from playing your character to its full potential. Levels of your heart come fast at first, but the costs become prohibitive when you get up into level 20 or so. This wouldn’t be an issue if the most powerful Azerite gear didn’t require reaching level 22 to unlock even 75 percent of their full damage, leaving players left out of features from gear they’ve already collected. This means more grinding.
The greatest potential for going from 25,000g to the gold cap of 214748g is transferring servers. However, this also presents the greatest risk and needs the most preparation. First off, transferring costs money. If you go to a server, transferring back as soon as the cool down is up is expensive and impractical. You should look for a server that you can stay on for at least 6 months to a year before transferring back with your huge profit. However, the maximum amount of gold that a max character can transfer is only 20,000. Therefore, you need to purchase goods that are going to net you the most profit when you go to sell them on the new server's auction house. Primarily, these are enchanting mats, but can also be BoE epics depending on the two servers. Before making a risky decision such as transferring, consult the questions below.
That being said, there are occasions when a little kindness is not unwarranted. A typical example is a new player who just dinged level 20. They are suddenly confronted with a whole set of relatively expensive skills at his or her class trainer, and the cost of mount and riding training, and needs a small amount of money to learn those new skills. Likewise, sometimes one sees a player who, just by the way he or she walks, is clearly a new player. Kindness to non-whiny, well-intentioned, legitimately inquisitive newbies is karmically rewarding, and one should not worry about shelling out an occasional boon to such players. Remember, at that level, a few gold can go a long way. Heck, even a few older bags that you have lying around collecting dust in your vault will often be much appreciated.
Once you have your finished product and have a price for it, keep in mind that using either your faction AH or the neutral AH also costs money: if the item does not sell, its deposit is taken by the AH; if it does sell, the deposit is returned, but a cut from the payment it taken by the AH as a commission. You must factor this into your selling price: your faction's AH will take 5% from your sale, while the neutral ones will take 15%. You can factor this into your cost to determine the minimum price at which you need to sell to at least break even:
