Chop willows and get 99 wc on the member account. Another way to junk trade from f2p to p2p would probably make maple long bow with bow strings then sell to f2p account, you make profit/exp. Just get the supplies yourself.
That's probably because more than half of the guides sold are totally fake >_>. Fake, as in, "OK LOL GO AND GET JUNK THEN XFER IT TER UR MAIN, ENJOY DIS 'ERE GUIDE THNKX!!1!11!1".
Most good methods are P2P, so get your NONS membership first. Then buy a guide or become really good at getting someone to tell you one, Blue Dragon Scales was a way, although they are going down in price now, so you shouldn't really use that.
