What I Do Is Make Mith Bars, I Dunno If You An Do That Yet Or Not But What I Do Is Mine Mith And Coal Ores And Superheat Them On The Spot So I Can Carry More To The Bank. By Doing This It Saves Time. Besides, You Lvl Up Your Smelting Magic And Mining All At The Same Time. For A F2P Area I Recomend The Edgeville Dungeon. Another Thing I Do Is Make Strength Potions. This Isnt A Very Good Way To Make Money But If You Find The Right Person, You Can Make A Lot Of Gold. Sometimes I'll Save Up A Lot Of Runes Like 6k Fire Runes And Body And Airs And etc. And Sell Them All At Once Thats A Good Way To Make Cash. Well I Hope That Helps...
