I am looking to put together a sell thread and was wondering what the best way to know a good fare price for a figure?
What I do is look up completed eBay auctions. Read the auctions that succeeded and try to get a general price of the item that sold.
I usually check what people are bidding them up to on ebay, and then set my price lower, people want a better deal than what they go for on ebay. That's often why they buy them on message boards, That's what I do.
