I have been considering selling again on Ebay but will only use FedEx or UPS as I think their confirmation system is better and seems to be better with customer service than the USPS.
You might want to rethink that one. We use both FedEx and UPS in my office, and we have more trouble with their tracking systems that I have ever had with USPS.
BY the way: FedEx and UPS offer ACTUAL tracking of packages. The only actual tracking available through the USPS is with Express Mail. The rest is just delivery confirmation which is sold as exactly that: confirmation of delivery (not tracking).
Good luck if you venture onto eBay again.

eBay/Paypal need to do a better job of protecting those of us who purchase fakes thinking we are getting the real thing.
