Yesterday, Goldclover hit 65s on Dath'Remar in bulk, and I hadn't seen the price even close to that since pre-4.0.1. A fantastic chance to not only make some coin, but get a decent sample size for determining yield.
Ink of the Sea / Mill : 1.24 (1.48 for Adder's Tongue)
Snowfall Ink / Mill : 0.14 (0.25 for Adder's Tongue)
Absolutely awful for Snowfall Ink... which is usually the bane of an Inscriptionist's workshop, however I'm trying to stockpile it, since I have an ink exchange program happening as well as churning out those cards for some reason. /winkyface
Sticking with the assumption that Ink of the Sea's market value is half of Snowfall Ink... You want to make sure you are picking up Goldclover at 3/4 of the price of Adder's tongue to get the same value from milling it.
