You can sell your item and leave bulk feedback on eBay in a few steps including taking photo with phone camera. Natively! My wife is an eBay Power Seller. She has to spend hours to leave feedback for buyers. This app helps eBay power sellers to leave all feedback with one click.
You must login, Click "I Agree" and then Click "Done" button before use.
How to Setup this application? see http://www.ifomia.com/ebay/
If the first time, the eBay authentication does not work. Just quit the app and try it again. For some reasons, I have to try twice to get the authentication work for me. It is due to eBay issues. It does not apply to everyone. Sorry for the inconvenience.
