with all the problems people have shipping eggs with the USPS, why use them? Is there a reason not to use UPS or FedX? My 1st 2 boxes of shipped eggs came without problem, but this last box looked like it was used as a football and then driven over with a large truck. The side was ripped open and packing was falling out. The small box inside as also somewhat crushed, and I was sure I would find several broken eggs. I could not believe all the eggs were intact, a testment to the great packing of the shipper, (bargan/ Nancy of Garry Farm). So, why not UPS or FedX? Price? Take to long? Maybe no better handling?
