USPS Sunday service is horrible! When I track missing Sunday packages on
the USPS website, I always get the "Delivery Attempted" message. The
late package usually shows up with Monday's mail. As others have said,
don't depend on Sunday deliveries.

Recently had a FedX come a day late. They had the address a digit off,
89 instead of 87. They found me in their records and delivered the
next day. Do-Do happens.
