Its been a while since I shipped eggs, remind me how to do it please. I used to wrap each egg in a strip of bubble wrap and then wrap them in bunches in a box with packing peanuts. That worked out well but I'm up to suggestions. I used to send them out from the post office but I'd like to learn of better/cheaper options. I will only be sending a dozen plus at a time. I remember somebody mentioning flat rate boxes, where would I find these? Is it best to label the box with a "FRAGILE EGGS" label or to write nothing at all? What carrier is best; USPS, UPS, FedEx...? Thanks!
