I want to show another example of why its good to use the market... my last one wasnt so good...
Example: Purchase a Fireshield +100 (armor)
At the Armor Smith you can purchase a Fireshield for 1,294 gold.
In the market, after careful selection and some patience you (and I did) purchase a Fireshield +100 (w/ +14 Armor) for 600 gold. saving approx 694 gold.
Now flip side... I'm want to upgrade and get rid of the Fireshield the Armor Smith will only give me 324 gold but I can go to the market and list it again for whatever the market will bear, probably 600 gold again. So buy and sell at the Armor Smith and lose 900 gold or go to the market and at least break even or maybe even upgrade for free... Weapons the same...
Not so much really with the Alchemist. Upgrades seem to be hard to come by, at least so far upto level 7. A +1 damage grindstone at the Alchemist is 66 gold.. but at the market they run about 200-250 gold because they are limited... +2 can be 1000 or more
Not saying the Market is for everything, but if you dont at least look and compare you're wasting your gold....
