In this short and simple guide, Ill give you the basics of Flip merching, but you will have to figure out what items to flip merch. Cant give out mine!
To start, you must use all of your cash. It would be best if you had atleast 2m to start. Buy all of the item below med, but not at low. Youll have to experiment with the buying price by buying one of the item first to see what price it buys at.
Spend all of your money on the item, and wait 4 hours, until you can sell it back. When selling, go above med, and to the highest selling point it will go. Again, you will have to experiment with the selling price.
After you have sold all of the item, use a new item, because you cant buy back the item for another 4 hours.
Examples of what to flip:
Runes
Food
Ores
Bars
