I recently sent out a shipment that contained one Flat Rate Priority
Envelope, 2 boxes of comics, a 30lb box of laserdiscs all marked Media
Mail, and a 55 lb Laser Disc Player they were picked up just like any
other shipment no hassles with just the ...
As long as your long boxes do not weigh more than 70 lbs each they will
pick them up. There is a 70lb maximum for each parcel. I just sent 2
boxes today over 30lbs. each, one of them Media Mail.
They don't specify a time, but they always have come in the same 1-2 hr
window after lunch here. You can choose from a drop down menu where you
want them to pick it up. At your door, by your front door, back door
ect.
