I love this thread, and the profit is pretty amazing.
I personally don't need clans to help me as I've been averaging around 10m / day flipping with around 450M cash. ( not including my 15m+ every time the GE updates due to my buyouts. )
I love your profits man! How much are you eventually going to be paying for the lot?
I don't find clans very respectfull due to them "scamming" the lower players of runescape, but at the same time it's very hypocritical of me to say this, because If I were to be making profits such as the leaders do, I wouldn't give two fucks about all the D med, Granite plate, D legs kids.
Best of luck merchanting!
Once you learn to merchant you wont "need" these clans for things such as these, But nontheless there is great profit to be had doing this!
