HOW DO I FIND OUT WHAT TO SELL ON EBAY - THE FIRST STEP
Another tip for Ebay success is to make sure you do your due diligence up front. Selling on Ebay is great fun if you don't intend to make it a full time business. You can collect items laying around your house, go to ebay, type your item into the search bar and see how many others are selling what you want to sell.
If you really intend to sell your item on Ebay, you will need to create an Ebay sellers account (click here to do that) Once you have created an account (a sellers account) you will want to redo your search. The next step will be to type the same search term into the search bar and then click on advanced search and look down the page for the words "completed listing". Once you find that, put a check in the box beside completed listing, scroll to the bottom of the page and hit search.
What this will do is bring up a page of your items, but you will see that some of the items have green numbers. Those green numbers represent items that have actually sold on Ebay. Take those numbers and see what buyers have paid for them. That way you can get an idea of how to price your own item to make it competitive in the Ebay sellers market.
