Had no mail Monday due to weather and 5 delayed packages from Amazon showed up today....
Monday was a holiday for USPS. No mail. Same thing next Monday for New Years Day.
That said my friend just got a priorty letter that sat in Dallas for 3 weeks on it's way from Corpus Christi to PA. I've had lots of priority tracked mail take over a week, and my work send a check from Pittsburgh to my house (20 miles) on the 19th that still isn't here. Never use USPS unless you have to.
