Priority mail is a rip off. You can send a heavy envelope for less than half the cost of Priority. I get so sick of them saying do you want insurance, confirmation, etc. Not long ago I sent something Priority (4.95) and it came back addressee unknown. Called the party and she laughed. DH took a manila envelope put the same addressee & address on the envelope, mailed it for (1.90) and she received it. I will never use Priority again. I will use the Big Brown Truck.
