I am currently a power seller on Ebay, and I agree that smaller items that are cheap to ship seem to be the better option. Larger items are expensive to ship and sometimes harder to pack for shipping. It is also important to keep in mind that Ebay charges outrageous fees to it's sellers. They charge a fee on the total sale, which includes shipping costs. So the lower the shipping, the lower the seller fee will be. If you are new to Ebay, make sure that you calculate the seller fees correctly, as they can be a bit misleading. When I was a new seller, I lost money on several sales because I didn't fully understand the fee structure. Any new seller should add about 20% to cover the fees imposed by Ebay and Paypal.
