When a price rests on two sales far apart, it says so and names both.\n\u2022 A price card with the middle half of the sales for each condition, and a link to every price on gamepricefeed.com.\n\u2022 It finds the game however you write it: words in any order, with or without punctuation, 7 or VII, its other names, and the console.\n\nEach price is a guide, not an offer: condition, photos and the seller move it within its range. The buy and sell board lists collectors' own wants and sales.",
