Thats what i'm trying to explain in some other topic (how do you make money). Nice one :-). What Duke sais: dunno if its that difficult to understand how it works? Before GE you could make bigger profits (higher than 5%), cut some really nice unexpected deals. Now its everything "en masse". Predictable, but also reliable, and no hassle of looking for buyers/sellers. Just put it in the GE, do something else tada. So as long as you got a few 100s of mill to invest, you can make tons of money selling and reselling some random item (coal, yews, pure ess, iron ore, runes, ...) at a 1-5gp profit. precisely my friend. and it's VERY easy to predict where things are going with it... example: mahogany planks will drop tomorrow, pure rune essence will go up tomorrow, oak planks should stay neutral..they may rise/fall a tiny bit. chinchompas (regular) will stay the same/rise a little. red chinchompas will lower/stay the same. mostly all potions and herbs will fall. name an item and i can tell you where it's going, and how long it will last. i made 33M off of crystal keys because i knew the whole key would raise, the loop half would fall, the teeth half would raise...meaning buying the pieces separately would keep the crystal key value constant...waited until it hit max price (and i predicted it would top out at 74.5k...it did). sold all 3,000 crystal keys purchased at 60-64k each for 74.5k each...had a few left overs cause the key price dropped (as predicted) to 73.8k each...sold the final 100 for 73.5k each. i'm glad the GE is here...it's a fairly simple concept...but not as simple as "old merchanting" was. btw, sorry to any runecrafters for raising the price of your essence...that's my fault...i pretty much buy all of it for the max price so i single handedly control the market :-$
