Now, there certainly is demand for consumables (I myself have probably chugged down 100+ potions of speed by now) but as a general rule, I think it's fair to say that the casual demographic isn't going to spend 5g to down a boss one second faster and those in somewhat serious guilds tend to get consumables crafted to them for free by a guildie, or commissioned in bulk from a random with vastly lower margin of profit than consumables sold in auction house. I have my suspicions about the value of alchemy.
