We had an eBay store account years ago. Almost everything breakable got broken from the USPS. We complained and a supervisor said they have a disgruntled employee problem and have spies in their mail rooms looking for employees intentionally damaging packages. He said if you stick a bunch of fragile stickers all over the box it might intice a postal worker to throw the box for kicks. We dropped USPS as an offered carrier and our products stopped becoming damaged over night. UPS seemed to take better care of our packages. WE DID NOT SELL EGGS. JUST GLASS COLLECTABLES. US Post office is good for letters, nothing else in my opinion. If you order eggs on line, request UPS as a delivery service if possible.I'm confused, who do you mean?
