If you’re using paypal this will give you some protection as you can see when the money goes in before sending.
Also read the paypal and eBay help files for other tips on making a safe transaction. (There is also plenty of help if you do a Google search)
Remember you were a zero feedback once, would you have joined if you new you would not be able to bid on most of the items. (An auction site has to expand to survive)
Hope this helps
