There are items vendors sell that have a limited quantity only refreshed every few hours and sometimes days. When browsing a vendors’ inventory always keep an eye out for any of these. They can be gear, recipes, or even materials or potions.
An Overview And Things To Watch For
Limited supply items are needed supplies that you are not always guaranteed to obtain through a certain method. Whether it be purchasing from a vendor or killing for a quest there are many limited items waiting for you to make some profit with them. Light Feather is a notable one as it is needed by mages’ to cast some of their spells like slow fall and usually sell between 3-6 gold per stack of 20. Keep in mind after server maintenance there is a window where all the limited supply items from a specific vendor are back in stock so if there is something you want to turn a profit off of jump online fast and rush to said vendor.
A strong point on limited supply items is patch release day. Before a new patch is released keep an eye out on what content is added and what may be needed for attunement or maybe a change in a profession or class. Stock up on these items as they will be cheaper now than when the patch or expansion releases. After the said content is released inflation will hit almost immediately and this is your opportunity to exchange your foresight into gold. Never underestimate this tactic as it can prove very valuable to the vast amounts of gold it can yield.
With the evolution of World of Warcraft gear has changed and grown with it, this is very true for class armor or weapon sets. Anytime you pick up gear that is part of a set or for a specific class and you can not use it, and it is not BoP, there is much profit for your taking. Keep these items set aside and always try and sell them for as much as possible because they are rare and valuable to the majority of characters.
