Any postal workers on the board? Got a question or two...

Having issues with our mail getting delivered sometimes...not sure what the official rules are on when the carrier can decide not to deliver a package because it's 'too heavy'.

I thought the rule was under 70 lbs and not marked 'two man lift'?

Just had to pick up a 40 lb box at the post office that fit in a large flat rate box...

It comes down to the call of the carrier him/her self.
My Wife was a USPS carrier.
