TL;DR: Buy cheap herbs. Craft BoP shoulder enchants. Vendor them all.

I just got 1575 gold and 229 Starlight Inks for free with some milling.

I had 3000g on each 4 scribe (12000g in total), and I spent that gold for cheap MoP herbs (max. 1g60s a stack)
Milled all those herbs, and used all the Inks of Dream for crafting 724x Secret Crane Wing Inscription, which vendor price is huge 18g 75s.

So I had 12000g to spend, and after vendoring I got 13575g and 229 Starlight Inks in my bags.
If you are mass-producing Darkmoon cards like I am, then you're going to simply love this, but only if you can obtain herbs for cheap price.

I'm crafting 13 cards daily with no cost, actually earning a bit while doing this thing.
