I'm going to piggy back here. Do you need to sign for your MBs when they are sent US Parcel Post? I looked on
MDE and the tracking says they are at the PO ready for me to pick them up. There was no delivery attempt note on my door or in my mailbox. It just seems weird that I need to go down to the PO and get them. Maybe I'll wait another day and see if they show up today in my mailbox....
