Selling update: Nobody bought any of my crossbows, so I lowered the price
even futher. They are now only $1500 each! If you've ever wanted a cheap, top-quality crossbow, now's your chance. Crazy? Yes, but I need to get rid of these damn things.
Buying update: Big thanks to whoever put up the 5 iron for sale! I still need 10 iron or 30 hematite for my goal, though, and any amount helps.
How much for at least one plutonium?
I put mine up for sale for $250. Someone else put one up for $1000. If you really need them, I recommend snagging them before someone else does.
