i sent my husband to the post office with some eggs to mail today. they were packed in the same boxes that i received other eggs in. the box was mailed to me from missouri and cost under $10 priority.....but when i packed it (with smaller eggs, mind you) the cost from florida to pennsylvania was nearly $21! am i doing something wrong? my husband asked for priority mail with shipping confirmation. that's right, isn't it? the contents of the box was 1 dozen denizli eggs (medium sized eggs) in an egg carton lined with cotton batting. it was placed in another box and surrounded by packing peanuts. that box was placed in anther box, surrounded by packing peanuts and sealed. help! what am i doing wrong?
