Processing flips. Buy tradeable materials, make them into a tradeable product with a skill, and sell for profit (after the 2% GE tax). Recipes are verified from the OSRS Wiki — exact items, quantities and levels. Profit uses current instant-buy prices for both sides, so your real margin depends on the spread and whether your offers fill; you also need the listed skill level (and any noted one-time unlock), and this doesn't count your time.
