Instructions
Open your Internet browser and type http://www.amazon.com into the address bar located near the top of the browser window. (This is one of many places where you can sell items online. For other examples, see the Resources section below).
Scroll down the web page and locate the "Features and Services" subhead on the left side of the page. In this section there is a subsection titled "Selling with Amazon." Find the blue colored link titled "Sell Your Stuff" and click it once.
Click on the "Start Selling" button located under the "Sell a little" subheading.
Under the "Select product category" heading, select "Computer and Video Games." In the box next to the category type in "Xbox" and then click "Start Selling."
In the generated list scroll down until you locate the title "Microsoft Xbox - Video Game Console" and click the box next to it titled "Sell Yours Here."
Select your condition and in the box below, type in any specific details about the condition of the product (is it scratched in a specific place or is it chipped, etc). Then click the "continue" button.
Type in the price you are asking for your Xbox and the quantity (if you are selling more than one). Finally, check which shipping method you prefer, expedited or standard.
Enter your Amazon.com username and password to finalize your selection and list the item for sale. If you do not have a username or password you can quickly create one for free.
Sit back and wait, if your product sells, Amazon.com will credit your banking account (or give you a gift card if you prefer) for the total amount of your sale and provide you with a shipping address so you can ship the Xbox to the customer.
Keep in mind that you might want to explore other types of advertising to sell your Xbox. (See the Tips Section below for an explanation)
