Goblin Jigs sold by Goblin Trader?

Or, you know, you could sell fish and use the gil to buy lures from the MB.

Goblins are, as we know, a greedy, hoarding lot. Their fishers probably don't want to share their secret killer lures with anyone else!

PS. Goblin jig and bladed steel jig are made by GSM, not BSM. The price on the MB is pretty inflated, given how cheap the root materials are. A great example of economics in action! (demand driving prices and all that)

Or lack of supply since idiots like me who can craft it (you don't even have to be 60) don't do so because we are too lazy and/or don't know it's in demand.
