Clean everything, take a second or two to make sure the console and or games you are selling is clean and looks appealing. Spray the console with 409 on something similar, and get in all the nooks and cranny's to remove all the gunk and or dirt. Same goes with the controllers, clean the buttons, directional pad. Make sure what you are selling looks as if you would want it; if you were the buyer. It doesn't hurt to do the same with your game cartridges. I would recommend cleaning any cd games with a CD cleaner or something similar.
The Research, prior to just throwing your game on eBay and hoping for the best. Take a look around and see what the game is actually selling for. If the game only sells or has a buy it now price of about dollar, it may not be worth your time. Then on the other hand you could have a jewel, and price it accordingly. Make sure to price your items to sell, don't just stick a fifty dollar tag on a game when you can buy twenty others for fifteen dollars. This really is a successful point to sell video games on eBay; is product research.
Test your video games, I know it sounds redundant, but this is crucial to be able to sell video games successfully. Make sure to test each and every game, load each game, to ensure it loads properly. Then play the game for at least a minimum of five-minutes. To guarantee the game doesn't skip or freeze inappropriately. Remember to ensure before you sell video games, that each one plays and loads just fine. If selling any video game consoles, you must make certain all the components of your package work. So test the console to load and play games properly, then test the controllers: from each button, directional pad, start, and select buttons. It's vital to make sure the ac adapter works, and the audio video cable or TV connector cables function.
Now it is photo time, make sure all your photos are taken in a well lit area. This is significant to sell video games on eBay. If you have bad photos or a lack of photo's your video games will not sell or won't sell for a reasonable price. Make sure to get photos of everything you are selling in one photo. So if you are selling a Nintendo 64 video game console, with 10 games and two controllers. Get at least one photo with all the components, then take additional photos of the controllers, the hookups, and the lot of games you are selling. The more photos' the better, if you have any flaws, make sure you take of photo of that flaw.
The Details: before you sell video games on eBay, it is imperative to list every detail of the game or lot you are selling. Included any flaws; from a game my have from a torn label or sticker residue it may have. Or if the console has a name written in marker on the bottom. It's always to best to be as honest as possible with people, or it will come back and haunt you in the end.
Lastly; make sure to package the items properly. All too often sellers don't take the time to properly package what they have sold. Video games are electronics, and are very fragile. So wrap and consoles or accessories in at least bubble wrap. Send any game you sell in a quality bubble mailer. Never send the games or consoles wrapped in paper with no additional cushion. Paper does nothing to protect your item, and your video games will get ruined in shipping. Then you'll be out the shipping cost to the buyer.
