How do I make millions in runescape quickly?

This is a question that I get asked all too often. Players that already have a couple of million gold pieces, (possibly by following my "Make Money whilst levelling Magic?" post), looking for ways of increasing their Runescape money stash without doing any work at all. Many would laugh and tell you it's impossible, but they'd be wrong.

Rune armour sets are constantly in high demand because it's the best armour available to free players. This is excluding trimmed or God armour sets, but those are just glorified rune anyway.

Buying individual components and combining them into sets using the Grand Exchange clerk can make 50k in 5 minutes for very little work. It's important that you only try to buy a maximum 25 of each item (full helm, platebody, kiteshield and platelegs) at once, because the Grand Exchange will only let you buy 100 items of armour or weaponry every 4 hours.

Here's my video guide (best viewed in full screen):

Good Luck!
