I started on Ebay selling a couple suitcases, that sold. also bought the book Ebay for Dummies...which I am still reading and learning....
Hi Sandy and welcome to the forum
Great way to get started is by selling some old unwanted gear from around the house. A lot of people forget that Ebay started very much as a second hand market. Most tend to focus on selling new products now, but there is still a massive second hand market thriving on eBay.
Enjoy reading that book and just yell out if we can offer any assistance at any time!
