Ralph,I have been buying and selling for several years and always use the Post Office. Contrary to what everyone says about them,I have had only 1 item get lost and it was insured.You can ship 2 strikes with up to $50.00 insurance for$3.00 . That way you do have a receipt for your records.I just received payment for an auction thru Fed EX and their overnight service took 4 days!
