The amazing thing is that on Hades these sell from anywhere between 20k-35k/99. That's 20k to 80k profit on one stack of each material. If you sell them at the right time you can make quite a good amount of money.
Of course since Allakhazam doesn't add the year a post was made, I have no idea when you replied. That being said, toad oil is going for 6K *each* on my server, and a stack is 50K. So, since 4 stacks of these equates to about 64K gross in sales, add the cost of the other materials in, the net profit is about 2K if there are no HQ. Hardly sounds like a money maker to me. ;)
Also the prices are always changing so unless you find a post that is recent, i would say within a month, you cant even be sure if its true for current time
The reason that this is priced so high is because Toad Oil is a HQ2 Desynthesis of Tonberry Lanterns. If the Lanterns are common on your server, then these are probably not expensive.
