The best option for everyone is to RuneScape Gold continue talking, and perhaps jagex will come up with a different method to put their thoughts out to the world without spending huge amounts of money.
I was a victim of an item swap...i was a very low-level, but still at 50cmb. I wanted to train firemaking, and was buying huge quantities of yews from other players who had gp I earned from selling them to other players as well as fishing lobsters.
I was planning to buy roughly 20K Yewlogs. I was so angry and wanted them fast. Few players would pay me enough to get what I desired. Then someone offered me exactly what I required. He showed the logs for sale, and I put the money up.
The trade was cancelled, and i was traded once more. He said something along the lines "sorry for this" and then immediately sent 20k willowlogs to trade. Without double checking, i gave him a considerable profit for the garbage logs. Logs that I had used to teach firemaking were still available however at a much lower rate. This was a tragic loss to an F2P scaper who was fairly new.
It was a great learning experience for me, and I have been double-checking, often triple-checking. If you're not close to the limit of 2007 RS Items your buys, the Grand Exchange has helped to solve the issue. But, I am patient and will wait a few more days until I get the items i need in the GE.
