I am sending eggs to a friend about 1000 miles away. I can send them any day of the week (always picking the freshest to send). Would Monday be the best day, to avoid the package sitting somewhere over a weekend? Or does the flow of other packages and the modes of transportation make shipping on Fri or Sat better? I am planning to mail them via USPS, priority mail, with special handling. The special handling costs about $11 more, but I understand they put it into a basket and it gets handled gently rather than thrown around the facilities like a ball. Has anyone used this, does it help?
