Merchant by these ways

[smileshine]

Merchant by flipping. Purchase items and runescape gold with the intent of selling them within a short period of time. Purchase the entire stock of an item and sell the item after a few hours or days.

Merchant by price manipulation. Work with a clan, or group of people, to manipulate an item's price at the Grand Exchange. Purchase the entire stock of a particular item with the clan, making it unavailable to other rs gold players.

The demand for the item will rise, thus increasing the item's price at the Grand Exchange. After the item reaches a predetermined price, dump the item on the Grand Exchange and make a lot of cheap rs gold.
