Joanna, another ebayer here! I've bought everything from a tee shirt to a big screen TV on ebay. In fact, ebay is where I bought my laptop and my camera too. I've sold lots on ebay as well...it is adicting! Betty is right, start out with something small. You should also get an account set up with
www.paypal.com as this is the most common way to pay. Lots of us to help you with all these things.
