US video game retailer GameStop has rolled out a new trade-in campaign that lets you get a new Xbox One X for as little as $200.

The store is paying as much as $300 in trade-in credit when you trade in a PlayStation 4 Pro and apply the trade credit towards an Xbox One X purchase. The Xbox One X sells for $500, so applying the $300 credit means you can get it for only $200. Trading in a regular PS4, Xbox One S, or Nintendo Switch gets you $250 in store credit, which means you can get the Xbox One X for only $250. Finally, GameStop will pay $200 in store credit for the original Xbox One model when you apply the trade credit towards the purchase of an Xbox One X.
