This guide will help you merchant in RuneScape with Gold Exchange. It is now harder and slower to merchant but merchanting is still possible. You can still make big bucks with it if you follow my tips. All of these methods require you to have money already.
Rune Essence Merchanting
Buy Essence for 1k ess. for 20-30 gp each. You can also mine if you have no money and need some. Try selling it for 30 each or lower. This will give you enough money to begin merchanting other things faster. Iron Ore Merchanting
Go to Falador bank. Sometimes noobs will be mining iron and you could easily buy their iron ore for 50 each. If not try to buy iron at 72-82 gp each(currernt market price). Do not buy at a higher price than that. Sell it in Gold exchange at a higer price. Rune Armor Merchanting
Buy each piece of the rune armor. Even buying in the high price. Sell the whole pieces as a set. The set will always be more expensive and gurantees you a profit. This will take some time but will make money fast.
Those are my three tips. Hope they help you and give me feedback. A good price guide is necessary and a calculator is always handy. A website with a good price guide is here. Good luck and goodbye.
Best suggestion for every f2p are either telegrab zammy wines or rasie ur skills up... minning,wc, and runecrafting.
