The two ranges overlap, so there is slack whichever side you push — but they are cut from the same 2,685 margin. Spend it all outbidding and there is none left for undercutting.

These are limits, not predictions. Super antifire potion(2) last sold at 5,800 and last bought at 8,658 — 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

A super antifire potion is a potion made with Herblore that provides complete immunity to regular dragonfire for three minutes, as well as partially blocking the stronger dragonfire of Galvek and Vorkath. It may only be used after starting Dragon Slayer I. It can be made by a player with 92 Herblore by adding crushed superior dragon bones to an antifire potion, which grants 130 Herblore experience. With 98 Herblore, the super antifire potion can be upgraded to an extended super antifire with lava scale shards.

Alching it yields 280 after the nature rune, 5,520 less than it costs to buy. Alching it is a loss, so the price floats free of the alch value.

Measured with medians rather than averages, because one spike — an update, a streamer, a brief squeeze — drags an average around for weeks afterwards and makes everything since look ordinary.
