I'm starting a farm. You want silver, I want seeds. There's an obvious solution, yeah? So I'm looking for high purity, useful seeds:
Cereal - Wouldn't be opposed to really cheap sulfur.
Cabbage - Maybe, we'll talk.
Pumpkin - Dying for lead,
Cotton - ...maybe if you give me a fire sale price
Reply here or shoot me a PM with what you've got, and what you want for it.
