I am excited too! I was mailing my two large boxes out (yes, I know bad, but it had mattress pads, pillows and sheets) and she told me the new flat rate box is 12x12x6 (or 10) and is $10.95 for military and $12.95 for general use. She told me March 31.. two clerks said that.. Funny she is not my regular PO.. I have gone their a few times, but she OFFERRED this info when she saw where I was mailing (and of course I had to tell her about AnySoldier)..I just thought that was really nice.. should be able to fit more in there, that is about the size of the regular priority box now and I find myself using those more than the FRB, so this is good. On average, I was paying $14- $17 for the other normal size priority box..
finally, the PO doing something for the military!!
