Ebay is the internet's largest marketplace, and it's an excellent place for buyers to find what they want at bargain prices, and for sellers to find buyers. If you haven't posted an auction on ebay before, It’s fairly simple to post your first auction on eBay. Just do the following five steps.Step 1: Open an eBay seller’s account.Obviously, this is the first thing you need to do . If you’ve bought things on eBay, then you already have an account — just log in with it and click ‘Sell’ in the toolbar at the top of the page, then click ‘Create a seller’s account’. If you’ve never used eBay before, then you’ll need to open an account first using the ‘register’ link underneath the toolbar, and then click ‘Sell’ and ‘Create a seller’s account’. The eBay site will then guide you through the process. For security, this may involve giving card details and bank information.Step 2: Decide what to sell.For your first little experiment with eBay, it doesn’t really matter what you sell. Take a look around the room you’re in — I’m sure there’s something in there that you’re not all that attached to and could put in the post. Small books and CDs are ideal first items. Once you get more used to how things work, try to indentify which market is right for you.
