Things You'll Need
Instructions
Open your web browser and navigate to an online marketplace where you can sell used items. A few examples are eBay, Half and Amazon.
Sign up for a seller account and fill out all of the requested information.
Register your payment information. Half requires you to enroll a checking account so that you can be paid via direct deposit. To sell on eBay, you'll need to accept either PayPal or an E-Check from another service. Amazon will allow you to receive payments through direct deposit or Amazon store credit.
Take photos of your games---one photo with the cases closed and one photo with the cases opened. This reassures the prospective buyer that you do, in fact, have the games you are selling.
Create listings for your used games. Amazon and Half require you to set fixed asking prices for your games. If you're using eBay, you can either set "Buy It Now" prices or list your games in auction format. This will allow buyers to bid on your games, and whoever has the highest bid at the end of the auction will win the item.
Ship your games out quickly when they're bought or won. This will make your customers happy and get you some positive feedback from satisfied buyers on the website you're using to sell games. The U.S. Postal Service's Media Mail option is the least expensive and will get your games to their buyers in about a week.
