So send all your Q0 stone to SLV Power Corporation for 26.50 caps each and your contract will be accepted!
However, please send a maximum of 100,000,000 Stones per contract, but you may send as many contracts as you like!
This is the equivalent of selling for just under 30 caps each on the market (which isn't possible because of the NPC
), so sell to me by contract and gain extra profit!
