I have found some people willing to sell invented potions to us as a guild in bulk for lower than Auction House prices. For the most part, they are lower and they guarantee to have plenty of supply due to them limiting sales to guaranteed buyers (whole guilds). You don't have to buy from them, but I will update the price and keep negotiating for a better deal and selection weekly.

Buff - Potion - Price (gold)

DC 225 - Black Death - 175K
LB 225 - Bookworm - 180K
BK 350 - Potion of Fury - 175K

The DC pot is not the best deal out there, but I am promised it will be flexible with the market and will drop in the future.

Sellers who agree with these prices:

nice and i don't have to use fsp

Well, I am sorry theses guys have gone out of business due to higher level players undercutting all their selling prices and over paying for components.

If I hear anything else, I'll post it here
