Merchanting (or "Flipping") is the art of buying items for a low price on the Grand Exchange and selling them for a higher price, passively generating millions of GP while you train skills or log off.
How the Grand Exchange Works
When a player attempts to insta-buy an item, they often put an overwhelmingly high price in the GE to guarantee they get it immediately. Conversely, when a player insty-sells an item, they put in a deeply discounted price. Merchanters act as the middlemen. We provide the liquidity. We place patient buy offers at the low prices, wait for them to fill, and then place patient sell offers at the high prices.
Finding Your "Profit Margin"
To flip successfully, you need to find the "Margin". The margin is simply the gap between the actively traded Average Low Price (what impatient sellers are dumping for) and the Average High Price (what impatient buyers are paying).
Historically, you had to manually price-check items in-game by buying and selling one item and losing money. Today, you can use our OSRS.LOL Prices Tool to instantly see the live tracked margins for every item in the game without wasting any gold.
The 2% GE Tax
The Grand Exchange has a 2% tax on all item sales. The tax is deducted automatically from the seller's revenue upon completing a trade. It caps at 5,000,000 GP per item sold.
The Golden Rule: An item is only profitable if the Margin is strictly greater than 2% of your Sell Price! Our live calculator automatically subtracts this tax for you, ensuring you only see pure net profits.
High Volume vs. High Margin Flipping
There are two major philosophies when merchanting your GP stack:
- High Volume (Safe & Active): Buying thousands of cheap resources like Runes, Logs, and Ores. The margin might only be 2 GP each, but moving 20,000 of them nets you a quick 40k. These items trade incredibly fast, minimizing risk.
- High Margin (Slow & Risky): Buying expensive, low-volume PvM gear (Elysian spirit shields, Twisted bows). The margin could be a massive 5 Million GP, but it may take 12 hours to buy and sell. If the market crashes overnight, you lose millions.
The 4-Hour Buy Limit
To prevent aggressive market manipulation, Jagex enforces a "Buy Limit" on every single item. This is the absolute maximum amount of a specific item you can buy across any 4-hour window. For example, the buy limit for Abyssal Whips is 70. Once you buy 70, the GE will not let you buy any more until a full 4 hours have passed since your very first purchase.
