Retailer GameStop has announced a "Trade Anything Day," and as part of this, people can visit a store and trade anything. Well, not quite anything. There is a list of items that GameStop will not accept, including dead animals and illegal drugs.The fine print for the December 6 event states that people can only bring in for trade items that fit into GameStop's own 20x20x20 box and that employees have discretion to reject any item.In terms of the specific exclusions, GameStop said people cannot bring hazardous waste, weapons, dead or alive animals (taxidermy is OK, though), alcohol, tobacco, drugs (illegal or otherwise), "sexual and explicit" items, or items "resembling body parts." The full list of exclusions is available on GameStop's website.It is unclear how GameStop will determine trade-in values for some of the odd items people may choose to bring on the day. But in any event, people should know this is a marketing campaign first and foremost that is meant to bring people to GameStop's stores to drive sales and awareness.In other news, GameStop is among the numerous retailers that is not raising Xbox Game Pass prices, so you can still buy one month of Game Pass Ultimate for $20 there. GameStop specifically has pledged that it will not raise prices, at least not yet.
