Started item flipping on Runescape (F2P)

So i started item flipping on runescape and this is some results.

For those who dont know what flipping is here is a short tutorial.

Look for an Item HERE that is going UP in price, then once you have found your item login to Runescape and go to the Grand Exchange and buy ONE! of your item, but buy it for double it's mid price, then note down how much your got it for, this is your HIGH price.

Now go back into the Grand Exchange and sell your item for 1GP and note down how much it sold for this is your LOW price.

Now you can buy your item in bulk for 1GP over your LOW price, Then once you have bourght all your items sell them for 1GP BELOW your HIGH price. and watch the profit!

You can do this with any amout of money just starting with alot will make you alot.
