Instructions
Trade-in your old GameCube games. Some game stores, like GameStop and BRE Software, accept these games for trade-in. Most game stores offer store credit for trade-in games, though some may offer cash value.
Sell the games online. Sites like eBay and Craiglist allow you to put your old games up for sale directly to interested consumers. The advantage of selling your games directly to a buyer is that you can often get more than the trade-in value, though you may have to factor in expenses like shipping costs.
Give the games away. Ask family and friends if they want them. Or, try giving them away via local mailing lists, like Freecycle, which coordinate giveaway items with people seeking them. Charitable organizations, like the Goodwill or St. Vincent de Paul thrift stores, may also accept video games.
Recycle or dispose of the games at an e-waste facility. If you have GameCube games that are defective or damaged, recycling them is your best option. Some big box stores, like Best Buy and Target, have electronics recycling, including optical disc recycling for video games. Organizations may sometimes hold electronics recycling events where they accept optical discs for recycling or safe disposal. You can also call your local waste disposal provider and ask about e-waste options.
