I'll update this as I need to buy or have things to sell.
Currently I am buying Tears of Sea Kin and Diamond Pieces from the mobs in spring of love in lundagrant. 40-55-ish should be able to get them easy and one of each per mob. I'll pay a decent price for 'em (decent for both of us) and I'll buy like 10-20 of them. So, if you got some or wanna get a little cash please let me know!
