Buy Small Stacks, Sell Big Stacks

I was at the Auction House today, looking at Primal Earths. They were available in stacks of 1, 2, and 20. The stacks of 20 were going for about 100 gold. On a hunch, I did some quick math, and discovered that I could make my OWN stack of 20 by buying all the smaller stacks, but it cost me 30 gold LESS to do it that way. I then turned around and undercut the other stacks of 20, and earned a 25 gold profit.

This is a good example of how the average World of Warcraft player makes mistakes, especially ones who haven't read and gold earning guides. ALWAYS be on the lookout for easy scores like this! It works with primals, enchanting items, cloth -- anything that can be stacked!

Of course, this can work in the opposite way even more effectively. Rather than rely on a stupid player paying more for a stack when they could save by buying separately, you can take advantage of the deal seakers! Just keep an eye out for big stacks of items - in order to make them sell, players tend to sell stacks of items for LESS money per item than the ones for sale individually. For example, a stack of 20 Adamantite Ore might be up for 20 gold (1 gold per ore), while individual listings will be up for 1.5 gold per. Just reverse engineer this by buying these discounted stacks, and breaking them into individual stacks to sell at a higher price!
