Just as an aside, I acutally put most of the boards with questions about already priced items into Help & Questions instead of locking them outright. It can be a bit of an irksome rule (actually I often leave threads open here that only have one item priced at 50mill, just for discussion purposes), but that's the way she rolls! :)
I will go ahead and lock your board if you're not using it anymore, but if you have a question in the future about an item that seems to be priced oddly, feel free to make a board in Help & Questions! :)
