On my server I can routinely make 100 of these every couple days and sell them for 5 g each. Since they are used by many raiding dps. I spend about 2.5 to make each one (with out any procs ). With procs I am spending about 2.25 ish each pot.
I sell them in stacks of 5 and list them about 1 hour before common raid times. This ensures I am the lowest price on the ah. I also use a 12 or 24 hour auction so I can save them to relist on the next major raid night on my server.
They sell alot less often than potions of speed, but there are some people who still use them.
