Estimation estimation

1. estion that a lot of people new to the auction house face is what stack size to sell items at for the best profit.  So many players choose too big or too small a stack.  Here I’m going to explain how to pick the best size and how to take advantage of those who get it wrong.
2. You should always ask yourself why you’re selling the item when considering the stack size.  Is it a consumable that they need lots of during a raid such as potions, or one that lasts longer such as flasks?  Will they use the mat for mass crafting or need a small number for a specific recipe?  Is it a one off item?
3. When listing items for mass crafting/profession levelling I find listing large stacks works well.  This is especially true of Legion mats which I find sell best in 200s.  You may find that older mats sell well at 200 as well, particularly to players who are levelling professions at the same time as levelling their toon, but given that professions can now be levelled from 1 to 800 entirely with Legion mats, lower level ones may not sell in bulk as well as they used to and instead players may prefer to buy them in small amounts for specific recipes.

5. For materials that are used for certain recipes it’s a good idea to list them in a useful stack size to make it convenient to the buyer.  Most would rather buy a single auction for the number they want than have to make it up to that number in smaller stacks or buy too many items.  For example Living Steel is best posted in stacks of 4 for using in the Jewelcrafting panther mounts, while Trillium bars are better in stacks of 6 or multiples thereof for transmutes to Living Steel.

7. I list enchants and cut gems as single items as the majority of players want to buy these individually when they have a new piece of gear that needs to be enhanced.  There’s little point listing these in stacks.

9. When you list items at the optimal stack sizes you can often add a mark up and still sell even if there are other stacks at a lower price.  The convenience of buying a lot of herbs in stacks of 200 rather then individually or in small stacks tempts buyers to pay a little extra to save time and clicks.  Check the price of the small stacks and consider buying them to combine into larger stacks and sell for a mark up.
10. Even if you don’t do this, always check the price of the optimal stack size when undercutting, not the less useful stacks.  You can even do this automatically if you use Trade Skill Master- check the “match stack size” box and it will only look at auctions of the same stack size as you have set when calculating the price to post at.
