USPS ground, all the way across the country, for a P4 recently cost me $19, but I did not pay to insure it, and I shipped it bare, without battery, transmitter, charger, and props. Just the styrofoam case in a larger box. It arrived in 7 calendar days. The fully insured price is close to $40-50 and gets it there faster. But, somehow, DJI gets it to me all the way from China in 3 days without breaking the bank!Just had a P3P shipped to me from half way across the country via USPS 3 day priority was shy of $16 so there may be a cheaper shipping option then UPS but I realize its also distance that effects cost
