Today i found out how to effectively sell a stack of coal for 500 Nz. All you do is purchase 8 stacks of sand, smelt it, and sell the glass. The sand should run you about 1500, and the glass should sell for around 2000, and all you have lost is a stack of coal, therefore 1 stack of coal =500. therefore by the same logic, 2 stacks of coal= 1 diamond, if you buy it from the store. With coal being the most abundant ore in the game, and with it being possible to get a whole stack from just one vein, and with coal not being sellable in the game, this is a very handy glitch. It's not even a glitch, its like a loophole. Roughly 8Nz per coal. Im not sure if this is already done en masse here, but i just discovered it, and made 3000 from a few stacks of coal people gave me for free.

Thanks heavensords. Also, if foob adds coal or charcoal to the shop, and if you can buy it for less than 8Nz, infinite money loophole created. Say it sells for 4 each, stacks of coal from the shop are now worth only 250 by the aforementioned technique, but infinite. If one has the furnaces, one can make infinite money in a relatively short time, especially with help. I think Joe will not add coal however, simply because of this post. But if he does, free money, and therefore free diamonds! There was actually a time when charcoal was on the shoplist, i think it sold for 3? maybe im wrong, but charcoal was definitely on there, if only we had known sooner!

You could also go into SP and hack yourself a million NZ.
But whats the fun ?
I always go for the fun of mining, that warm feeling when you sell your hard earned ore's.
Not to mention that a little physical workout is good for the body......oh wait...I am mixing my worlds up again.

Its not cheating though, i think the warm feeling of finding an ingenious way to get money is far better than the feeling of selling your hard earned ores. Plus it would take some MASS furnaces and mining coal to get much money out of it. I did 32 furnaces burning sand into glass and only got 2048 profit lol
