Please - I didn't post in the advice master thread.
It's for a friend. When he asked me I didn't grill him on his business model but I'll call him back and fix him.
I think that gives us the answer. mancunian's friend is in the esrog
business. He's shipping 3 large boxes of esrogim. Not 3 esrogim. A virgin seat is just over $200, 3 baggage approx another $100. So he gets cross country, one day shipping at less than $150 a box.
