Here you can post items that you have crafted, or that you have found in adventures for other PCs to purchase from you. There are, Unfortunately a few rules that must be obeyed so that we don't crash the economy.
First of all, Prices must not exceed book value. For example: A Light Crossbow cannot be worth more than 35gp if you make one to sell. A Masterwork Light Crossbow cannot be worth more than 335gp if you make one to sell. This must also remain true for items that are found. BOOK VALUE PREVAILS AS A MAXIMUM.
Secondly, I realize that there are items that don't have a set "Book Value" Such as Jewelry or Clothing. Well - For mundane items, there is a cap of 100gp on Jewelry and 10gp on clothing. Other items will be added to a list as issues occur.
Thirdly, If you are making something to sell to the NPC Market to make coin - Don't. That is what profession and skill rolls for income is for. You're not going to spend 50gp, make a roll and scoop up 100gp for making a ring and selling it to an NPC. This is purely meant for PC to PC sales.
Fourthly, The Auctionhouse Thread will have items posted on it regularly, and PCs may bid on them. There will also be an IC Auction for quick purchases, and in these IC Auctions, You are welcomed to have the Running DM place an item up on auction for you. Rules for this will be posted.
