While I appreciate that the specifics of the use of the Flat Rate Envelope are a bit on the absurd side (70 pounds?) Americans will find that even a more prohibitive restriction leaves us with far better postal rates than most any country. With the exception of shipping bulky, weighty objects, like raw wood, the FRE is a bargain. Neither UPS FEDEX or DHL will deliver a pen across country for me for $4.60. As for wood purchases, If we need to go to the $8.95 Flat rate box, it's still a great rate.
