Where can you buy half priced potions?
I am constantly in need of new potions in Inferno and I have to invest quite some gold in this. Buying 10 potions costs 6.100 gold. This is not much but it adds up. Especially jumping to a higher Act burns through my potions.
I think I remember some NPC selling cheap potions after some event, but I am not sure.
Is there some way to buy potions for less than the common vendor price of 610 gold?
It does not matter if this is very rare, as I would buy like 300 or more at a time.
