Auction house prices

Auction house

• A sell never starts at a price that would pay you no more than a vendor does, after the house's fee
• Selling for no more than a vendor would pay you asks first
• An item's guide price is the middle price paid for one over the last week
• When nothing has traded for a week, the guide price is the last trade's, with its date

Reference

• How trading works says what the guide price is, and that selling for no more than a vendor pays asks first
