Difficulty: Moderately Easy
Step1
Create an eBay seller's account by following the onscreen instructions. An account will allow you to buy and sell items.
Step2
Do a little research to find out how used Game Boy games are priced. Use eBay to look around and find out how much other people are selling their games for. Are they being sold in packs or as singles?
Step3
Prepare your games for sale. Clean the game cartridges if necessary. Take inventory of the games you are selling. You might want to make a list or a database for recordkeeping.
Step4
Click away. It helps to have pictures of your games. If you are selling your games as a group, take a picture of them together. If you are selling them all separately, take separate pictures. Since people buy with their eyes, pictures will help sell your games.
Step5
Write a description for your items. Writing a separate description for each game will be worth the extra effort. Have someone else read the description to be sure it makes sense.
Step6
Post your auction and watch the bids come in. Since selling on eBay is an auction, check in on your item often to see what the bid is up to. It will run for a certain amount of time before the auction is over.
Step7
Get your cash! When the auction is over, the high bidder will be your winner. The easiest way to get the money from the buyer is by using PayPal.
