FREE guide to making LOADS of money

How many of you are tired of mining, fishing, cutting wood, smithing, etc. to just make big bux!? If you dont care about raising your XP and just want to make TONS of money in a fast way, this guide is for YOU.
I havent played runescape for little above a year now and decided to share my money making strategies. I dont want to be cheap and charge money, so this guide is COMPLETELY FREE. This guide can be used by BOTH members and non-members. I was a non-member myself. This strategy has turned me into a millionare with a lot of rare items including the very rare DISK OF RETURNING which i bet some of you haven't even heard of. Anyways, Ill stop blabbering and get to the point.
This guide is short and not a gazziliion pages long. Im not gonna go "round the bush". You need to have atleast 50k-70K in cash to get significant profits. The more cash, the better.
THIS IS WHAT YOU DO....
STEP 1: Find "best seller item(s)" and forum.Depending on the market, you will need to find out what item sells a lot in the game. For example, COAL has always been one of the "best sellers". Then you will need to go to a runescape forum. There are many runescape forums including the official runescape forum, runehq.com forum (idk if it still exists) and MANY other private forums. i suggest you get hold of multiple forums to increase your chances.
STEP 2: Find sellersOnce you get hold of a forum(s), you want to find sellers that sell the "best seller item" for the regular price. For example, COAL sells for about 150gp or so. You want to find sellers that sell in a huge quantity (in bulk). Keep track or make a list of these sellers.
STEP 3: Find buyersNow comes the tedious/fun part. Now, you must find buyers that buy the same "best seller item" , but for a higher price. For example, thee are buyers who buy coal in bulk for 170gp when the ongoing price is 150gp everywhere. Trust me, you will definitely find these kinds of high payers. It just requires a little bit of looking around. I have found many of these kind of sellers. Keep track or make a list of these buyers.
STEP 4: What to do with these sellers and buyers I kept track of?Now its simple. With your cash, buy the most you can from the sellers. The more you buy, the more profit you will make. Once you have bought the "best seller item" in a vast quantity, sell it to the "high paying" buyers you kept track of. Its that simple.
Now I bet most of you are thinking, what a jackass this guy is. This will never work. Trust me, THIS WORKS! Oh it really does. Many including me have used this method and many still use it today. It takes less than an hour to find sellers + buyers. Then your on your way to make some BIG BUX!!!If this didnt work, I would never make this guide.
