Sometimes you can swap normal for gold

Ok so markets are really weird place. Normally gold are going to cost y9u three times... but sometimes they don't.

Wavesmiths have shot up in value, in fact they are sitting at almost $10 a pop

Now let's look at its gold friend, which starts at level 2

Ok so first thing to know if 5 normally level 1 wavesmiths are need to make a level 2. So at current prices a level 2 is going to cost $50.. the same price as a gold level 2!

So what I did was sold the 5 normal wavesmiths I had picked up for $49 and bought a level 2 for $51, effectively buying a level 2 gold Smith for $3. The advantages are 400 more gold power, twice the rental of 5 level 1s and 5% bonus everytime I play it, which I often do!
