No wonder USPS is loosing their astrict... RANT New stop Dallas Texas!!! Grrrr!

So we go in today to ship some aluminum wheel spacers USPS.They are in a small priority mailing box (not flat rate box). It is slightly larger then the small flat rate box, 1/2 the size smaller then the medium flat rate box. The say it will be $29.00 to ship, but if we put them in a medium flat rate box ( box twice as big) it will be $12.00.
So now they wasted a bunch of tree's on boxes,besides the cost of 2 boxes, and it's going to take twice the room for them to ship.
If it were up to me, I would have charged for the larger medium flat rate box, slapped the postage on the smaller box and shipped it. But no, we have to drive 5 miles home, and re-package it, then take it back 5 miles........That is government!
