The two ranges overlap, so there is slack whichever side you push — but they are cut from the same 48,799 margin. Spend it all outbidding and there is none left for undercutting.

These are limits, not predictions. Extended antifire mix(1) last sold at 200 and last bought at 49,998 — offering exactly those joins a queue at a price that has already cleared. How long you wait depends on how many other offers are stacked at each price, and the Grand Exchange does not publish that to anyone outside Jagex.

About this item

Extended antifire mix is a barbarian potion that provides 12 minutes of dragonfire resistance and heals 6 Hitpoints. It is made by adding caviar to an extended antifire(2), requiring level 91 Herblore and giving 61 experience. This mix can only be created after completing the Herblore part of Barbarian training with Otto Godblessed, and it may only be used after starting Dragon Slayer I. When used with an anti-dragon shield or Protect from Magic players will be completely immune to certain dragonfire.

Its high alch value of 96 does not cover the 155 nature rune it would burn, so alching is a loss before the item itself is counted.
